There is a screw for almost every application. I cover some of the basics necessary for understanding the advantages of the modern screw.
I can't find my parachute bag on amazon. The one there appears to be a cheap knock/off of sorts......would love it if some one could find out if the real ones are still available somewhere. I'll try and get some pictures up!

Thank you, be safe, and be grateful.
Very informative. After watching this video, I feel like I graduated from Screw U.
Very punny.
bugoobiga LOL!! Congrats grad!
congratulations......... The next class is-(Screw you two)
bugoobiga u
Haaa good one
Is it just me, or are the woodworking fellas and ladies of YT among the most well spoken Americans this side of the Ivy league lot. Gotta love somebody who can communicate clearly and peacefully.
I just watched a 9 minute video about screws, and I was enthralled the entire time.
I could listen to this guy talk about carpentry for days!
Love your channel! Surprised to see you here.
Yeah really good
And look at that shop!
Have you seen Larry Haun?
I could listen to this guy talk about carp and trees for days
as an almost 2 decade residential and commercial framer and carpenter I can assure you this man's advice is beyond invaluable to any homeowner or entry level craftsman. Thanks for providing your hard earned knowledge. ps I just bought a Burke bar. done without one for 17 years and instantly understood the applications when I saw it in your hands. Just like the press and your friend, I will think of you every time I use it. Thanks man
I love the learning from this channel. It just so happens I purchased a parachute bag after seeing this video.
I had one a while back and didn't know what to do with it. I put it in the bottom of my tool bucket for a while but that wasn't useful at all. I keep so many fasteners with me I have five snap together organizers, three with screws and two for nails but I think I'll give the parachute bag a try again now that I know what it's good for.
I love this channel, I watch ec for chill out I'm before bed, and obviously learn. Wish he was my neighbor.
@@massey-rn8mq yep, that would be a neighbor to have.
I've been working mostly in the remodeling construction trade for 20+ years. I haven't done much framing and I learned a bunch from one of these videos. I'm mainly a tile guy, flooring guy, drywall guy, ECT. But with the company I'm with now, I have to learn everything. And honestly, I'm freaking excited that I get to learn the stuff that I don't know. LOVE THIS CHANNEL!!!!!
I am teaching the next generation of carpenters here in Pasadena, Texas. I use your videos constantly to teach because I love how concise you are (and entertaining). Thank you for the entire series. I'm driving up your views by a factor of about 50 kids every year. Thanks for all your help and insight.
I learned more about screws in the last few minutes than I had in my entire life before. Thank you for posting this video. :)
Thomas Jefferson I cannot believe Mr. Jefferson needs to use screws...
Me 2
I didn't know the ghosts of dead presidents liked watching educational construction and carpentry videos
Me too.
I have screwed almost everything. This guy knows how to screw.
that screw display is a thing of beauty.
I’m 25 years old, and I still practice pounding nails into scrap in my garage. Love using the nail guns, and boy do they speed things up, but everybody should still know how to pound a nail by hand, efficiently.
@ stop your dirty way of thinking
I wish I had more
Agreed. I still do math on paper for fun sometimes. Everyone should know how to do math; it’d make this country kick ass again.
Same here. I like using hand tools sometimes even when I have the power option. It feels like you gain back some aspect of it that's lost with power tools or something.
If you ever do siding it's essential because you need to leave a gap for expansion
Probably the only CZcamsr that can get me excited to watch a video called "Screws...". Keep doing what you do!
I look at him more as a philosopher then a carpenter...99% of stuff he talk about I know I won’t do but I just enjoying listen to it...
Good dear
He does have a verbal eloquence, doesn't he?
Thanks for the walk down memory lane, I still have my yankee screw driver somewhere in the tool cabinets. How things have changed, I had 40 years in the trades and loved every minute of it. Was a GC in residential construction, the last 28 years. Keep the videos coming. God bless.
Back in 80 I started to make furniture in an old timers one man shop, he was 67 and I was 18 boss only had hand screw drivers, so I hacksawed the handles off and mounted them in a corded 1 speed no reversing plug in drill. He later went out and got me one that reversed.
idk who makes your videos but the production quality is insanely good.
I'm almost the opposite of you, sort of. I'm a semi-professional musician/songwriter who recently discovered carpentry and home repair. My wife and I bought an 1880 Italianate Victorian home 2 years ago that has become my art project. I also started working for a contractor friend and have learned so much in a relatively short time, that it gave me the confidence to rip apart our bay window roof and reframe it in preparation for my own, hand-cut and shaped copper shingles. I've enjoyed your helpful tips for reference along the way, and appreciate how you present them via your production techniques: They're to-the-point and no nonsense- (some of the things I'm starting to implement in my own music videos.) Anyway, I liked you before, but I have a newly found respect after learning that you were a fellow musician. Keep it up.
I do carpentry myself and the one best takeaway from this video...is that parachute bag!! Thank you for that tip, sir!! I do pole barns for a living and I also do corrugated metal roofing with the galvanized insulator screws, so I end up with these getting mixed in with the 16 pennies I use for kick plates. I also build and tear down concrete forms and end up having to get a separate pocket on my belt for them, since you can't use them in structural work, as you stated. Parachute bag = no problem
More of these info vids! Im an apprentice, i find these so good for learning more and more! Keep up the great work!
We are all apprentices...never forget that!
I can't forget. Construction is ever re-inventing itself. There will always be something new.

@@x-rayzulu5643 What?
Thanks Essential Craftsman. Now I'm properly educated for when I get screwed!
Great vid Scott. As a 40-year geologist, handyman, and furniture craftsman myself, I always love watching salt-of-the-earth souls like you who have made their living outdoors and under practical means about how to build and get things done. Just like Norm, Tom Silva, and the TOH tradesman gang! And especially so around the Fall and Winter months when hot cups of coffee from my Stanley thermos begin either my fieldwork or shop days amidst the crisp air and/or snow. Keep on trucking!
One of the most well thought out explanations I’ve seen in recent memory regarding torx screws. Loved this video.
I love these videos so much. I wish you had your own television show
He does, it's on CZcams a couple times a week!
When I was growing up we moved a lot. So Dad built a number of pkywood boxes for kitchen, linens, etc. But he drove the screws in with a hammer up to a point, then used a Yankee Screwdriver to seat them. Now with him gone I sometimes have to repair those boxes.
Thanks for this video. I'm subscribing to see what else you do that I can learn from.
Thanks so much for putting this video and others like it together. I walk into the store and I have no idea about the type of screws I need for a given job. This is awesome content and frankly, for someone who didn't have the upbringing that you were blessed with, it is full of quality information to help us along in our journeys.
As an average guy, not in the trades but I build my own home, I haven't built a deck in 25 years. I recently built a small set of outdoor stairs and when I went to buy hardware to attach the ledger board to the house I couldn't even find the 1/2" hot dipped galvanized carriage bolts that were traditionally used. I was pointed to the GRK Structural screws instead. I bought them and checked out the specs and schedule online. Wow! What a difference and so much easier, I didn't even have to go into the basement for anything. The ledger board isn't going anywhere. I also decided to use stringer brackets along with the special screws from the bracket manufacturer...so much faster and easier. I'm pretty good at hammering, getting a lot of practice building wall sections for a builder one summer at age 15 but I've always hated pounding joist hanger nails as it can be difficult in a tight area. Great innovation not only for installation, but also for repair-ability too.
So interesting. I love these kinds of videos! No bs, just information and quick!
Just bought my first drill and THIS was the video I needed. Thank you! You rock ⚡️🙌
55 yr old carpenter here. All my life. Even back in infant school the caretaker would bring in wood so I could ‘put it together’. I love my job as much as I can see you do. Recently subscribed to your channel as it’s a pleasure to watch. You explain everything so simply and straight forward. One thing I will say.. you made me realise just how much stuff I do know. The kinda things you take for granted. Common sense stuff. I hope someone takes care of my tools when I depart. 😀👍
immediately bought a parachute bag after watching it's been extremely useful no more screw spills and always have the screws I need available instead of having to go to the truck to dig for them
Over 20 Years I've been a general contractor... I find this man's video's incredibly informative and I learn something new with each one he produces. I really look forward to each and every video and watch them all... sometimes even binge watching...lol
Lol, yep
..YesSirRee, those GRK are wonderful!! Pricey, but worth it. As long as the threads get a bite, they will pull slap thru a board...
As a life long garage carpenter I have to admit your page has finally answered so many of the basic questions guys like me have thought about for years. I just started watching but wanted to thanks you for a great idea and look forward to more of you videos.
Your videos are such a joy to watch. Was looking up information on hammer drill reviews and ended up watching your videos. Thank you I appreciate you sharing your knowledge and skill.
The thing I always liked about the square head (Robertson bit, if I remember right) is that it sticks on the bit magnet-free, because of the taper. Super handy, as the mag's can actually work against you, and the torx don't stick unless you've got magnetism.
I was thinking, "I don't need to know this" but was very surprised how much I enjoyed it. Good education.
Yeah
I keep coming back to this particular episode.thank you for your well thought of video on this subject.you are part of my continueing education.
Just finished a 2400 square foot home completely with GRK screws. we were trying to recount the total number. The closest we can come up with is around 46,000 not kidding you. The only nails used was for the corner metal edging on the dry wall. I do think you have some of the best videos going. Keep up the good work. I appreciate your ability to get to the point no sense wasting words or the oxygen in doing so.
Just to add to the screw info, do not mistake Robertson for Square. They are two different driver/screw configurations. The square has 90 deg sides on both the driver tip and the screw where as the Robertson has a tapered shape to both screw and driver. Using a Robertson driver with a square screw will result in a loose fit more prone to slippage and stripping. Using a square driver in a Robertson screw will normally not reach the bottom of the screw and can result in Jamming your bit in the screw. To tell them apart often the sizing on the item will let you know what it is... 1, 2 ,3 = square, 6, 8, 10 Robertson or Green Red Black...
Love to see somebody that can signal a crane correctly very few know correct signals even old hands
I was going to comment on that. I think he could make a pretty informative video about signalling.
Jesse Howe that signal is extend boom
pancakeRgood I was thinking the exact same thing!!! He should definitely make a detailed video could definitely save a lot of people time, money and suffering from accidents that could have been prevented with a little know how on everyone's part.
A few years ago my coworker had his thumb caught in the chain. I didn't think the operator was watching my directions so I jokingly signaled boom up. Well just let me say it wasn't pretty to see what happened next.
So thats what that means in you signage,was wondering,,here in Auz we just use 2 fingers in a V shape to tally in or out,,depending on witch direction fingers up means boom out and fingers down is boom in,,for boom up make a fist with thumb sticking out,,again up is up and down is down,
Just thought you might find that interesting,,
Oh my gosh, I love your videos! We have a few things in common, graduated from HS in 75, was a timber faller for 25 years, worked in the timber industry for 30 years. During seasonal lay offs and Lay offs due to spotted owls etc I did handy man work and built a 900 sq ft addition on or house in the 80's. No you tube back then, just Sunset how to books, lol! Never attained a level of skill beyond that of a wood butcher! These videos would have been so helpful back then but still, they are such a blessing to me now as I do projects around the house! Thanks for doing what you do!
You are the first Carpenter I have seen that can signal a crane .
please please please upload as much as you can, I love your videos!
1:53 - What a cool screw display! And thanks for another super-helpful video.
I was Class of '75, so I'm probably one year older than you. Still trying to find a replacement copy of my yearbook.
What a professional this gentleman is!
I finished high school in 1980, always worked construction trades. I now work as a access control and lock tech, coming from the low voltage electrical field. I too, started in building remodeling, and have worked in many of the trades. I am very thankful for the work you are doing. I hope you keep doing these videos, as they are a chronicle of what has happened in our time, in North America, in the building trades. Thank you for these videos.
Thank you!
Yes, Ive fallen in love with GRK fasteners:-)
I wanted to build a rolling work table. The plans called for screws. I really didn’t know anything about screws and would have been inclined to use nails. The information here was very helpful!
This camera action was the best out of your all videos.
It delivered a thrill
Yes it did
I have no idea how I found your channel, but thanks for being amazing! You're like a father I never had.
I really appreciate your videos. At 30 with 14 years in a assortment of trades. I want to be like you when I grow up. Thank you for sharing!
Andrew Jones,
I don't blame you ! I am 14 years older than him and wish I had grown up like him ! I am afraid he is one of a kind. As his good friend Cy Swan.
Really interesting vid - thanks for putting it together! In the UK 90% of the time we use Pozidriv - they're excellent and never cam out if you use decent bits. I did a screw rust test vid a while back - the screws I commonly use are very corrosion resistant and never break - about $3 for 200 screws. They're very, very hard but not brittle. Would be intrigued on your thoughts - can send you a selection if you like?
What he's saying is that a screw provides more tensile strength (vertical, or straight pull), versus shear strength (horizontal, or side load) brittle has nothing to do with it. Harder the steel=less shear, softer steel=less tensile. at any cost the screw will provide more vertical or straight pull, than a nail because of its "bite" versus a smooth nail.
This is truly a craftsman go-to page for in-depth technical info. Thank you.
Dude, I just became a subscriber. I started my career when you did. But done different things in between. You are my go to, and hero!!! When I started in 1980, I was framing 500,000.00 homes, now I'm remodeling and building additions on $million plus homes. I am using you for a go to on some things. Thank you. I appreciate you. God bless.
A very professional presentation from someone with many years in the territory.
Love this guy. So knowledgable. I wish he'd do a video about everything we need to know about women too
@@Good-Citizen that’s gonna be a long video
Just bought my first set of Torx head screws this weekend repairing a shed behind the house I'm selling. Never used them before and wanted to see if they were worth the fuss. They were. I'm a convert now.
The trick is.. everyone that will work on your shed after you will either hate you because they're not Torx converts and they don't know what it is, or they will love you because they're also Torx converts.
I converted to square (Robertson) from Phillips. Torx is great with two major draw backs. 1.) it doesn’t sit on the bit as well as a square #2 which makes it more difficult to use when working by yourself one handed. 2.) for most general stuff you end up using #8 and #10 screws. For Torx that means having a T-20 and T-25 and switching back and forth. Both those common screw sizes come with Robertson #2 bit sizes making it easier all around for most applications I do.
GRK makes really bad ass screws and for structural applications, a T-25 and GRK or TimberLOK screws are where it’s at. For fences and sheds etc? I’ll use the square #2 bit and be done with it
@@nsatoday I'm with you on the TImberlok and headlok's. Worth every penny. I built a little bridge type thing access my mother's barn. She was using old pallets to cross the 'moat' into the feed room. Every now and then a horse would horse it's way into the feed home and destroy the pallet bridge. There's no way deck screws would have held up to that kind of stress.
I used them in an 18-wheeler.
Got to love working with Mr. Wadsworth! He is a true craftsman and very good at what he does!
When I built my deck I used screws on the 6x6 because I notched out the 6x6 to sit flush with my 2x12’s. The shear weight was completely on the post. I felt screws were better since the wood took the shear weight. The screws will help with shift weight
Torx is absolutely the way to go! Nice one!!
Hilti makes better concrete screws. More expensive, but for formwork, can be used over and over and don't break as easy.
I also love DeckMates coated screws for general building projects.
Excellent. Screws are the kind of hardware I have discussed most with my son in law. I will be sending this to him.
You reviewed and answered my questions, and confirmed my observations.
Thanks. Oh and glad to hear some of your bio. I am more than five years your senior.
Have worked in the woods and forestry too.
You really like talking to your daughter's husband about screwing?
Got the hands of an honest worker
Can you do a video of what size nail to for different jobs?
everytime i need three different tips to remove one temporary board, i have a 'talk' with the crew. now a video on the werid wonderful world of nails!
Most people do not understand the variety of fasteners required to build a home ... it is all about fasteners. Torx all the way ! Another great video.
simple to understand and like how easy the explanation flows out so natural.
oop, your tool is showing at 7:52 lol
Quality youtube comment!
haha
oh myyy
Is that tool Rigid??
Pat F lol yeah the yanks screw everything up, good ole us of a, interesting bombing babies, Christian eh, interesting.
6:12 Ah, so that's what those screws that look like tiny missiles are used for.
Just now viewed this most informative piece. Thank you for sharing knowledge acquired hands-on and on-site, much more valuable than the academic BS. I am going back to remove and replace some of the screws I recently drove in a couple of DIY projects around my home. I commend you for devoting years to the trades and for giving us your wisdom. Thank You
Absolutely agree with you about GRK... the only screw we'll use in our off cabin kits production. Only thing I have against them is that they have so much pull in torque that they will pull right through material. You'll get some overzealous wild man driving the screws half way thru sheathing... essentially destroying the connection. We use a lot of the RSS version wide heads for exactlly that reason. Now they really hold...
That's honestly mind-blowing that screws weren't much of a thing just 50 years ago.
No impact drivers.
Been using them for decades. Robertson invented in the 20 s before the philips. Best screw going. Very little cam out and can stay on your bit without falling off.
Thank you for calling it what it is: "TORX" ...and not "star drive" like a rube. Robertson gets an honorable mention too.
There actually is a difference between Robertson and square drive screws, Robertson has a taper to it while square doesnt.
@@grizoh The Robertson screw should have been the de facto standard. The genuine Robertson screw has a square centre with a slight taper it can be held on the bit without falling off. Having used these for ????years never known one to strip or fail...If Phillips the salesman had not conned Ford into using his screws and Posidrive had not put too many angles in the screwhead to facilitate cam out then the rest of the world would have the benefit of Robertson screws. In Canada they are the tops.
I’ve just discovered this channel and i love it. Outstanding work and tips with great explanation! Thanks.
Nice and organized film. I used many if not all of them at one time or another. It is great to know that you have put this information together and given an narrative as to the use and explanation of the variety of fasteners. Thank you for making this video.
Have you ever thought of a shop tour? came across your channel great stuff thanks
I used some of those yellow screws on a redwood fence. I took the screws out perhaps 6 years later (replaced wood fence with steel fence). They looked pretty darn good. I re-used them.
I find that the yellow screws snap less than the drywall screws.
Also I believe the Lox head (modified square drive) has greater torque capacity than the Torx head.
Square drive works just fine, though not quite as good as Torx (star bit). I can put my #12, 5" long stainless screws into wood pretty reliably with a good impact driver and a #2 square drive recess. Actually, the screws themselves tend to warp because the particular alloy of stainless that they manufactured this batch of screws with is overly soft. There are a great variety of hardnesses in stainless fasteners. The Simpson Strongtie stainless screws are top notch - no warping and the heads aren't nearly as prone to snapping off)
ciao.
As an operator, those hand signals need to be a video on their own. If not already. More folks like you would save so much frustration.
that last 30 sec does ¨Tim´s Tool Time¨ proud with positioning of the cordless drill and the banter.
My ex wife taught me all i needed to know about getting screwed.
sounds like you needed a good wood chipper at one point in your life...lol
Yea really! Slaved 10 years in the underground mines all so that she and her new husband can enjoy my house.
We flat heads will never learn. I suspect their is a Hex in there somewhere.
I hope it wasn't one of mine..:) LOL
Rule #1 never get married no matter what
I'm a Machinist-Welder, I hate wood (Lumber) and it hates me. I butcher it occasionally only out of pure necessity. Up till about 2 years ago I never paid attention to other screws besides Drywall screws and used them for everything. Then I discovered Deck Screws. Then I discovered SPAX screws. Wood work goes a bit better now.
Spax FTW.
Hello!
I'm a BC Dept of Labour Certified Carpenter, passed my exam the 1st time! This is a great video lesson for good woodworkers of any age.
@@friedrichuckhauff7046 yes, SPAX screws!
Yep, life is better with the correct tools and fasteners.
Very good channel in my opinion, soooooo much information about everything, and I like how the camera give you a close up into every detail. Thank you sir and keep up the good work.
Made me an instant subscriber.
love your program , just watch in my relax time for relaxing . Thank you .
never knew screws were harder than nails. never really thought about that. thanks!
Yep, but remember, Nails are still better for "shear" strength (most often). Nails will bend and still hold, Screws break quite easily when shear force is applied. Both have their uses. As a carpenter, I believe that both serve very different purposes, and are both very necessary on any job site!
PeteBillings yeah, ive always used nails for shear nailing. screws for dry wall. what would be better for cedar decking? seems like nails always seem to work them selves out some, so my thought would be screws?
So the saying should be "as hard as a coffin screw" then?
Adam Kreutzer I have repaired many decks over the years. I live in Texas the combination of extreme heat / sometimes excessive moisture and usually several light freeze thaw cycles usually does a number on exterior wood surfaces not much survives unscathed here. When repairing I usually tend to replace whatever the original builders used with pressure treated wood and deck screws with torx tips. One hint if you are simply refastening an existing board due to nail pull out it is a good idea to drill a pilot hole slightly smaller than the diameter of the screw through the deck board and just starting into the support. This way the screw does not split the deck board and fastens firmly into the support. The screws with the smooth shank above the threads will pull the deck board down nicely. Do not overtighten. Impact drills will do this in a heartbeat.
Actually, mild steel have less ultimate shear strength then carbon steel. So same diameter screw have greater shear strength then same diameter nail (core diameter, not outside diameter of threads).
It is just our impression that screws are easy to brake, because it brake in an instant, while nail creep. But you must pump up the force that breaks a nail to break a screw.
But... same diameter screw is much more expensive.
These videos are amazing, and I can't wait to binge watch all of them. Thank you for putting these together.
That being said, I got awfully nervous at the end of the video when the guy was handling a lifted load by hand. Please be careful. Attach a rope to the load (not the lifting slings) or use a hooked pole if you need to control the load and prevent swinging, but don't touch it. Being that close to a lifted load puts you way too close to the line of fire if the load is dropped.
Great, informative and enjoyable video. Thank you for sharing your knowledge and experience.
Awesome video! Clearly explains screws ...... and now I got to find myself a parachute bag!! Thanks for posting
Drywall screws are fantastic .... for drywall! Love your videos, as allways. Edit: I like Robertson's screw bits obviously you're correct they were an obvious improvement over Phillips. But they were also a lot less expensive then the Torque screws. I didn't mind paying for torque when I had large screws to drive. But run-of-the-mill decking screws? Not so much. In any event, your analysis of the capabilities and limitations of all of these fasteners is absolutely flawless. Well done as always.
My thought too, I've gone through many many boxes of drywall screws they are perfect for drywall heads above nailing, but not for use for anything else.
Lot of good information
This video could be a training lesson! I appreciate your time making it
This guys is awesome! I love watching him, learn more from him than any man I’ve ever known. I wish I knew 1/8 of what he knows🤩
i just have to add this, drywalls screw are pretty much different from ALL other construction screws when it comes to hardness. a drywall screw has zero plastic deformation before breakage. everything else will bend.
The screw driving tool at the end was what my father called a Speed Driver.
He built boats and had several speed drivers.
He used Monel screws for boat building.
The holes were predrilled with either an electric drill or a handcranked driller, then the screws were driven with the speed driver.
Interesting that no-one ever thought to use the electric drill to drive the screws!
Until someone did......😀👍
I love the deep knowledge and observation skills of this man 👍😁
Very well done explaining different types of screws.
Omg that is the longest/tallest freaking screw I've ever seen in my entire life!! I've never seen that type of screw before!! 🤯🤯
ok then Bubbi, consider yourself "screwed"!
@J Hemphill guys we never used those in my construction or woodworking classes and when I went to construction job fairs and built bird houses, we used either small screws or medium screws not insanely massive screws like those no of course not.
@J Hemphill exactly man.
@J Hemphill true. I’d give my left nut to be able to dovetail like expert carpenters
Great video!
I too have come to the same conclusions you have. Would you mind making a follow up video about load, notching wood to support load (such as in fencing) vs relying on deck screws or carriage bolts to support load vs just attaching planks to posts?
As usual, good and useful information from a trustworthy source. Thanks!
You are a master !!! i discover today you channel yesterday and i can't stop to surf over your videos !! my english are limited sorry, im not mother language, i just learn english by my self during my hamradio activity since i was a kid, many yrs a go lol.. btw thank's for sharing your knowledge !
Greetings from Italy !!!
the yellow is zinc plated with a yellow dichromate acting as a sealer.
isn't zinc is typically silver? Could it be Cadmium? Cad comes in at least two varieties, Cad 1 is silver and Cad 2 is golden/yellow.
@@flyingAMT I don't know but here is what I found at www.gattoplaters.com/yellow-zinc-plating.html
Yellow Zinc Plating
Yellow Zinc Plating refers to the color of the chromate that is applied after zinc has been deposited on to the surface of the part. Yellow chromate prevents the zinc from corroding and increases the overall protection of the finish.
This finish provides a rainbow or iridescent appearance with dominant yellow tones.
Benefits of Choosing Yellow Zinc
High performing corrosion protection
Cost Effective
Cosmetic Benefits
Considerations
Hexavalent Yellow Zinc is a traditional finish that was widely used because it was cost effective and provided excellent corrosion protection. Due to the European Union’s Restriction of Hazardous Substances Directive (RoHS) which banned the use of hexavalent chromium, the usage of yellow zinc has declined and is no longer allowed in products sold by many large original equipment manufacturers (OEM).
Trivalent Yellow Zinc is an alternative for companies in need of a RoHS compliant Yellow finish. Although it offers a similar iridescent yellow appearance it can be more costly.
A high performing alternative to Yellow Trivalent is High Corrosion Clear Trivalent. This passivate does not produce the same yellow appearance, but it is RoHS compliant and offers high salt spray performance. In some applications, it may be more cost effective than Trivalent Yellow. This finish is a widely used alternative for applications that previously required yellow hexavalent chromate.
@@flat-earther No matter what they use for plating they are indoor used floor screws not shear screws like the GRK's ! Using them outdoor or for framing its like imposing a short expiration date on your projects ! there's a proper screw or nail specifications for every specific applications ! Fortunately here in canada the building code and permits inspectors know a lot to spot carpenter taking shortcut on proper screws and nails for load-bearing wall , lol otherwise you would have all these newbies building house with cheap gyps screws only ! I've seen people trying to save on nails and screws using cheaper gold indoor floor screws to attach their galvanised bracket on their patio deck imagine what the chemical reaction will do to these screws after just a few months plus these brackets a recommended to be attached with galvanised 1 1/4'' shear strength nails only !
Is that known as galvinization?
No... the yellow sink plated screws are not as good as galvanised screws. It’s a different process and appears to be much thinner.
I remember working with my Dad on site when he had a Yankee screw driver. Haven't seen one for a long long time.
I still have one and I use it for light work or if the battery died on my impact or drill gun.
I’ve been throwing Phillips screws into the garbage every time I come across them, Robertson is my ‘go to’ screw!
Always very interested to hear your comments, your presentation is excellent thank you
