I recommend setting the speed of the video to 1.25x it puts a little more pep in his step and won't make you want to fall asleep as easily
Thanks 😂
2.0x here
yeah, I moved up to at least 1.5x. LOL
Tbh, this is my first time going 1.5x lol, I'm grateful for the explanation though too
2.0 🤣
I would love to see a new video concerning the selection of hardware concerning corrosion resistance/ tensile strength/ shear strength in equivalent size fasteners and the difference between the same grade fastener and different diameter such as grade 8 bolts of various thicknesses.
Great video. Very clear and easy to understand. Thanks
Good information, thanks for taking the time to make this.
You're welcome! Thank you for your feedback.
I have a Hex Cap Screw from a CB Antenna Mounting stud which I need to replace with a longer one to fit my application. The head is marked with "S30400 THE". A Replacement recommended on a forum has "F593C THE" on the head. What are those designations? What type of stainless steel mentioned would be a good replacement?
It will have very minuscule contact with an aluminum mounting plate; for grounding purposes. Will that be a problem or should I ground it in another way? Thank you.
Which one would be good for a cylinder head for a car engine
You didnt mention anything about tensile strength, or shear strength. Isnt that a wee bit important? I actually stayed awake for the entire video.
Hello Kirby,
Unfortunately, we did not talk about shear or tensile strength during this video. While both of those factors are, as you stated, very important to fastener installation, we found that it would be very difficult to lay out specs as they would change based off: Material, grade, type of fastener and the diameter of that specific fastener.
Due to the variability of the specifications of each fastener, if you have a question related to a specific fastener's tensile or shear strength you can contact our customer support department who would be happy to find these specifications for you.

@@AlbanyCountyFasteners Unfortunately, there is little "Understanding Fastener Grades" if these are NOT covered. Pretty much all that was covered, twice, was markings and coatings. Nothing to add to 'understanding'. Suggest changing title to Identifying vs understanding. We spent time playing with magnets but no item even mentioning why a grade 8 is different from grade 2. I do not recall grade 5 even being discussed either.
If you were talking about an allen bolt or socket head cap screw, and it wasnt a socket head pan head or conical head, one would "assume" it had the cylindrical head. What would you call this one? The cylindrical head socket cap screw? Thank you.
According to the Fastener Black Book (amzn.to/2Ad8ay4), which is the industry standard and is known around our office as the "Fastener Bible," those screws are simply known as socket head screws.
Very informative
Sheer bolts for snowblower augers, are they typically grade 2 to avoid damage? Is it ok to use grade 5?
Shear bolts, for snowblower augers are bolts designed to have a flaw so they will break if the auger gets jammed to prevent other more costly parts from straining and breaking.
While we do not currently carry them, it appears they come if a range of different grades. This probably depends on the size and power of the snowblower. It would be best to check with the manufacturer to find out which grade you should use for yours. Sorry we couldn't be more help!
@@AlbanyCountyFasteners
You were of great help! I like your thinking! In a jam, use lowest grade possible. Or better yet, dont get to that point. Always have sheer bolts ready to go. The newspaper guy can be annoying when that paper hits the auger. My latest john deere has a 59" blower. If you get bored (which is doubtful running an awesome business) I shot some snowblowing videos. Interestingly, when it was new on the 1st heavy snow, the snowblower driveshaft that attaches to tractor driveshaft, there is bolt that broke. On that shaft is akey way. I dont think the factory ever installed that keyway on the shaft. I didnt hit anything rough to sheer it. All is good now. Anyways thanks for your response! There are times when we want weak bolts!
What is the difference between a cap screw and a tap bolt? Thanks
Cap screws and tap bolts are the same up to a given size, depending on the diameter of the bolt. After that they diverge with Cap screws being partially threaded and Tap bolts being fully threaded. The diameter of the bolt effects when this cutoff point is hit (when the bolt changes from full to partial threading). Larger bolts tend to go full thread for longer lengths than smaller bolt diameters.
Here's an example: a 1/4"-20 x 6" Cap Screw is partially threaded, while a 1/4"-20 x 6" Tap Bolt is fully threaded.
Do stove bolts always have a slotted head or a Phillip's head?
Stove bolts always have a slotted head and resemble machine screws, but they usually have coarser threads.
We have gotten great fasteners from Albany over the years
Where did you buy those gloves?
hey I have a question .. I broke a bolt on my car that was a grade 8 yellow zinc bolt .. is there anything stronger than that ? I guess the torque from the motor is braking the bolt some how .. so do you recommend any stronger bolt ?
Grade 8 bolts are very strong, but can be brittle. Often in automotive applications you will see grade 5 bolts used because the bolt itself has more give than a grade 8, which makes it less prone to snapping. There is also a grade 9 in high strength for automotive applications, however we do not currently stock them. Of course, I would consult the manufacturer's guidelines on the motor for safety concerns before you do anything besides a direct replacement
@@AlbanyCountyFasteners thanks so you're saying I should give grade 5 a try ? and do you have a link to any recommendations ?
A grade 5 may bend rather than breaking off. some of the larger companies like Fastenal have grade 9 bolts, though they are significantly more expensive due to the high amount of heat treatment that is applied to the steel.
@@AlbanyCountyFasteners I rather pay the price .. I dont want this bolt to snap again .. so if you got a link it would be greatly appreciated .. I'll try to look for it tho
@@AlbanyCountyFasteners never mind I found it.. so I'll try the grade 9
What is the difference between a carriage bolt and a plow bolt?
Carriage Bolts are made specifically for wood applications and plow bolts are for heavy machinery. Plow bolts are commonly used for this because of their flat heads. To learn more about all the different kinds of fasteners, check out our Fasteners 101 Reference guides: www.albanycountyfasteners.com/Fastener-Education-and-Information-s/1128.htm
Hi Bab, how can I know between the carbon steel bolts and stainless steel?
🧲
What about cap screws for 20”-30” butterfly valves
How are other bolts with different types of heads marked so as to show hardness? (I.e. Robertson head, etc)
sae or imperial cap screws [ ie: socket (hex drive ) , button socket or flat socket] don't have grade marking as they are alloy steel . metric cap screws[socket] are marked usually 10.9 or 12.9 grade .
Great reply!
Thanks!
What is a Grade 2 bolt? What’s it used for ?
I just need to know whats the difference between the grade 8.8 to 10.9
Give this guy some coffee next time before you film a video haha
Christian Rankin Oh my god, painful to watch haha
I think it would take a hit of meth to liven this fucker up.
Edit: 5 minutes in and I can't take it anymore. The long pauses and repeating is too much. And for that reason, I'm out.
It's all good keep them coming.
It's all good keep them coming.
It's all good keep them coming.
so why in the world don't they put the same number of slashes as the grade?
So what is the shear strength of a grade 8 also is there anything higher than 8? Are grade 8 nuts the strongest?
Shear strength, and for that matter a lot of fastener specs, are dependant on more than just the material/grade. We would need to know the size, length, and type of fastener to give an accurate answer. As far as grade 8 nuts being the strongest, that depends on how you define "strong" and in what application they are being used for.
@@AlbanyCountyFasteners I nees something that can support about 10000 lbs for at least 20 years in the smallest possible size. I also need a bolt that is the most resistant to cutting.
Cool !!!
This doesn't have me understand fastener materials much at all. Why is a zinc coating used? what are the relative strengths of the different materials? Etc
An overall lousy presentation.
Gloves? Radioactive? Tender hands? Fresh manicure?
Thank you for your feedback.
Thanks,
You're welcome! 😄
Is 304 grade same as A2 grade ?
those are nice gloves. dont understand why you need to wear gloves to handle clean bolts, and I think ive discovered the cheapest anesthesia there is. Damn, I almost slipped into a coma watching /listening
I will see what I can do for the next video.
...where are the 12 line 'superalloy' bolts...?
This video only covers more commonly used fastener grades and materials. Superalloys are not typically used by the average consumer and may be covered in a future video.
Pro tip: Watch at 1.25x speed. Time is money.
I watch this to go to sleep every night. Never made it through the first three minutes yet.
Thank you for your feedback.
I almost fell asleep. LOL
Thank you for your feedback.
Playback speed: 1.5x
Thank you for your feedback.
1.5
When in doubt, use grade 8. Correct?
Grade 8 might be right for some jobs, but in highly corrosive enviroments or high pressure enviroments, Grade 8 bolts may rust or snap. There are other materials that would be better for those applications. The wrong material for the job may produce undesirable results. Take a look at our Fasteners 101 page on the subject of materials and finishes for more information: www.albanycountyfasteners.com/Fastener-Grades-Strength-and-Materials-s/1129.htm
1.25x
Lol. Sounds completely normal at that speed.
Genius... lol
lmaoooooooo
that's 14 minutes I will never get back. Is 6 slashes better than 3? He tells you what the grades are, but what grade is better than the other.
Only the magnet is magnetized
-1 what’s w the background noise, why not tape this on a factory floor
Because we are a working warehouse.
Bro just stick a chart and comment a bit . 1 min video
Thank you for your feedback.
So, what do you use the various grades of bolts for?
When do you use stainless steel bolts? Do you need anti-seize to prevent galling?
When do you use dip-coated bolts?
What the hell did you say in this video?
Nice idea, I don't reckon I learned a thing I didn't already know though.
Especially the info about structural bolts and nuts - and how about ratios and load bearing/torque ratings, calculations, thread calculations - like - how much torque can a given thread TPI of a given diameter of a given material take. - GIVE ME SOMETHING I CAN USE!
Respect your customers, or I'm just going to assume you're a bunch of slickshit salesmen who know nothing, just took a business management course sometime, well I can do that too.
And for goodness' sakes take some notes with you or go over what you're going to present, that really wasn't all that impressive.
Thank you for your feedback.
OMG...Are you for real?
It’s alloy, not alloyed
Thank you for your feedback.
Must have used larger magnet.
Thank you for you your feedback.
Im Bob......
Thank you for your feedback.
I'm bOB!
Thank you for your feedback.
2x speed is better.
🛌 😴 ⚰️
These are bolts, not screws.
Hi Mimo,
Of course, you are right, these are bolts. Unfortunately, the industry terminology is very messy and many people do refer to these types of bolts as hex cap screws. For example, we've also heard of them being called hex bolts, hex head bolts, hex head screws and hexagonal drive bolts. We find that most people have different names for fasteners depending on where they learned about them from.
Well, often they are called hex-head cap screws, as compared to 'socket' head cap screws...(allens)
Not great😢
A very disorganized and poorly thought out presentation. If you were one of my students, I would of failed you even if I were in a merciful mood. Did the thought occur to you to type up a logical presentation on a word processor beforehand?
Thank you for your feedback.
replace this guy witrh AvE then I'll watch.. *yawn*
Thank you for your feedback.
Who cares about the magnetism?
There are specific applications that require fasteners to be non-magnetic, such as in applications involving electronics and computers. When it comes to stainless steel fasteners many people think running a magnet over the fastener will prove its stainless or not. This is a common myth; stainless steel once worked into fasteners, commonly rivets and bolts, almost always have a mild magnetism due to the cold forming process.
Of course in an specific application there may be such a need - it was just that in the context of this video, which I would consider is more of a general nature, I couldn't think of any particular reason why it would be relevant.
Attraction to a magnet means it is mostly steel and therefore the bolt has magnetic properties.
