- Today I'm showing you how I use Fischer DuoPower wall plugs. These are the 6mm x 30mm plugs used with a 5mm screw. Used in concrete block, aerated 'thermalite' type block and 12.5mm plasterboard (drywall). As usual all tests are axial load tests showing peak values with no safety factor. Always follow manufacturer load ratings.

#TestTuesday #Fischer #Fixings - Jak na to + styl
Great video. Thanks Andy. I've used Fischer reds for years. After watching this vid I tried the DuoPower. Really impressed. You can really smack them hard into a 5.5mm hole without the mouth of the plug mashing over. Great for me when I'm feeling tired and haven't judged the hole depth too well!
I bought these today for use in plumbing (fixing shower fittings etc) and was very impressed. They pull tight and feel solid. Will be using these from now on, well worth the money.
Thanks to this video I started using Fischer Duo Power plugs, both the 6mm and 8mm size, on both interior and exterior fastening jobs. Pictures on interior drywall, shelving in the garage into solid brick and hanging basket plants and exterior decorations, house numbers and the like, outside on solid brick. They have been easy to use and so far I have a 100% success rate. Many thanks.
Watched this video a while ago now. But not really used these plugs. Last week though I fitted a kitchen using these plugs. Some walls were dot and dabbed and others were solid brick. Loved them. Managed to get the wall brackets tight on every wall. Whereas a lot of times before I've had to mess about trying to get a good fixing. They're great. Definitely going on every job with me now.
I found these wallplugs then found your review, it helped me no end, as a very basic DIY'er. It enabled me to select the right screws for the first job and the tip about making sure the hole was at least as deep as the screw was very helpful. If there is a way to do something wrong, I can normally find it, but today I hung a 90cm circular mirror and a Gin rack very successfully. Thank you
I discovered the duopower plugs when I was with my daughter "she insisted i buy them because of the funky colour" I was amazed how well they perform and became my goto plugs - thanks for the tests it reinforces my confidence in them as well :)
For the first time ever, a woman picking something based on only its colour has come in handy 😂
Thanks for the tip of using fully-threaded screws for these (and for posting the 5x40mm screws you used)… have had mixed results with these on DIY jobs (screw not tightening, plug spinning), and now I know why! Used a fully-threaded screw with a duo power today, it worked perfectly. Great vid, thanks 👍
I remembered watching this video last year. I have now reviewed it again, and now off to buy some now for a fixing into plasterboard. I will be using with confidence. Thanks.
No worries Brian! Remember I wouldn't particularly recommend these as a dedicated plasterboard fixing, there are better solutions. But these are a good all-round problem solver. Just watch the weight limits suggested by Fischer. 👍
Brilliant at last I've found real comprehensive tech reviews from someone who appreciates tech specs and data sheets, consider me subscribed bud
Excellent video and perfect timing with the info for some work I need to do. Just been put on to your channel and plenty of excellent vids on here, I appreciate your thorough testing!
Thank you Andy. Great tutorial as usual. I will purchase these plugs this weekend.
Great video. After a quick research I found out that DuoPower 6 (the one your are using) creates a knot like in your video. The one in the picture is the DuoPower 8
I hope to be helpful :)
Nifty bit of kit!
And great detail as usual Andy.
Cheers bud! 👍👊
Your videos are so helpful and informative ! Thanks so much for the great content. Using the duopowers in my new house I’m renovating and this video was invaluable !
Another great vid, been using them for 6months now and I like them.
Interesting what you said about push through fittings, I have little experience doing them. Would appreciate a how to vid if you get the time.
Thanks Andy. 👍
Incredible depthy review of the duopower, great commitment and great video, thanks
I use the DuoPower when I need a reliable fixing in tile/plasterboard situations. Saw them used on 10 Minute (ish) Workshop.
Thank you for your great advice. I have just bought a heavy Winmau dartboard. It's 5kg and my wall is plasterboard. I was all set to buy self-drilling screws until I saw your tests, and went out and bought a box of Dupower 6mm instead. Tentatively put up the bracket with two duopower this morning and the board is solid as a rock, even with my lousy DIY. Keep up the good work!
Great stuff! Just be careful as the constant movement of a dartboard (pulling darts out over and over) can exceed what these little plugs can handle. I'd normally use expanding metal anchors for something like this. 👍
@@GosforthHandyman Thanks, that's great advice. I will look to upgrade what I've done and remount the brackets as you've suggested! Cheers!
Excellent I’ll be using these plugs as I’ve just moved into a timber framed house & I’ll now be using the fully threaded screws thanks to you 👍
I’ll give those Fischers a go, never used them before and usually use the cheap plasplugs, nice one great review 👍
A great tip on the screw type, much appreciated
Great video without the screeching and grating voices of other youtubers. Excellent review and decent scientific method. Thank you. I hope you’re a Mag....top 10 finish for sure!
Good solid data Andy,you definitely need a white coat on test Tuesday though!👍👍👍👍👍👍👍👍👍👍👍
I''ve just stumbled across these since I bought me new home and the reviews I've read are really good, and now thanks to google tracking everything we do on here its recommended your amazing vlog, I've just ordered two types for my drywall to connect a wood frame to it, making a raised feature in my master bedroom. I'm I right in saying that the more I secure the wall with, then the max load is then evenly spread through out the fixings. So to hang a TV on the raised area the more the better. Thanks for the review on these buddy.
Hi Neil,
This is very late and you probably already got it sorted but yes. Each plug has a max 'weight' it can carry. If you divide the load over several plugs the load will be more evenly distributed :)
@@Tomskii5 thanks buddy and my tv wall is still standing six months on, thank you for your reply buddy
@@stomperthemixer1 dont worry if you buy a tv mount it is usually supported by at least 3 plugs. Each tv mount also has a max weight it supports. This combined with good plugs should be perfectly fine.
I tried to use drywall plastic anchors in masonry and the ones I had didn't work because they bent over before they were fully inserted. No problem, I thought I'd just go to Home Depot and buy plastic anchors for concrete. I couldn't find any labeled as such. I bought some anchors that looked like the plugs I had used before in masonry but they also were labeled as for drywall, but they worked.
It wasn't until I got on the internet and realized that the DuoPower anchors that Home Depot sold were duel purpose . I looked for a review of how well they worked and that's how I happened on this video. Thank you. As an aside, it seems like any anchor that you can get fully embedded into concrete will produce a much stronger connection than is needed for most routine light duty connections to concrete.
Impressive testing! Oh the joy of incomprehensible test results :-)
Great video, I was looking at these plugs but never realised it was quite so versatile. I have to say, I generally use the red EasyFix plugs form Screwfix at 59p for 100 rather than the £7 for 100 that the price is today for the duo. I noticed they do a Rawlplug red as well. That might be a test for the future that helps to show that whether the cost makes a difference. Just a couple of tests on each of the red plugs all the way up to the Fischer one? Anyway, Thanks again for the effort you went to.
Thanks for the video, Andy. I recently used some of these Fischer DuoPower plugs to attach some bearers to my garage wall to hold up shelves. I must confess that, where possible, I fixed them in the mortar between the bricks. I realise that this is not good practice, but the mortar is sound and gave a good, strong fixing. These plugs are good quality and they're working well for me. The shelves haven't fallen down and there's some pretty heavy stuff on them!
Great stuff - might do a vid about hitting the mortar vs hitting the brick. 👍👍
If you're drilling an internal wall that's plastered, you don't know if you're hitting masonry or mortar.
@@GosforthHandyman please do!
Been using the grey Fisher plugs (even the cheeper copy long before that from dial at the big orange warehouse DIY store and before that at the blue background with white letters starting with W.) So much better than basic plugs due to the square head to stop rotation. Great for brick, block and plasterboard.
Not had such consistent results with the red ones. I also tap them just below the surface with solid material as it's easier to plaster over when no longer needed, better than trying to dig them out and they can't be tapped in after use as they are solidly bonded in.
Good test. When I use these and the Fischer UX 6 plugs in plaster board cavity walls I drill the smallest hole possible, 5.5 mm in this case and use the smallest recommended diameter fully threaded screw. This helps stop the plug from twisting in the hole as you tighten it, especially in old softer plaster board. I wouldn’t use an impact driver ! and I usually finish tightening the screw by hand.
Yup - on all these test the screws were tightened by hand. 👍
Nice video, been using these awhile now without issues!
Nice video. I enjoy a bit of technical detail.
Brilliant review, genuinely helpful. Top man!
I've only used Fischer DuoFix to hang anything remotely heavy in my house. Absolutely love them. Especially the 10x50 plugs with 5xt0 bolts. They are pricey (5 bucks for 4 plugs and bolts) but its more expensive to replace a tv or two
If you look on amazon (and I'm sure elsewhere) they sell a selection for about $20 that come in a nice Sortimo box (and includes 15 10x50s, 30 8x40 and 60 6x30 - all with bolts/screws).
I love these anchors for plaster. Sometimes put in some 5 minute epoxy or insert scrap end of nylon tie between anchor and wall if it spins.
As I have now installed thousands of these, I wanted to reiterate two things from this video that are super important when using these: 1) If using your own screws, make sure no unthreaded portion enters the anchor; and 2) do not overtighten, definitely do the final tightening by hand. I've seen too many of these "blow up" because a worker took an impact to them.
You'll end up ballooning the anchor and it ends up mangled and spinning in its hole, which eventually requires drilling it out and installing a more time-consuming snap-toggle instead.
Hi Sakanora, I am curious around the importance of the unthreaded portion not entering the plug. In the video it's not clear why it causes an issue or whether it is only in the plasterboard scenario that is shown. Is it because a portion of the plug does not expand? If that it the main issue, then in solid wall this would lead to reduction in the load bearing relative to the length of the unthreaded portion, but the remainder of the length would expand. Or is there something else I might be missing?
Cheers Andy, this will be my go-to plug from now on. P.s love yr videos, keep em comin 👍
Your video was very helpful in choosing right plug
Love all flags on the wall.
Interesting video on an overlooked issue
Fantastic I need to hang a lot of pictures into plasterboard ,now I know what to buy 😀
Brilliant info Andy 👌
Love your video. Thanks. I will not be hesitating to use it on my wall any more.:)
Fischer Duopower are proven at fixing into Porotherm clay blocks too. A great allrounder!
I just do DIY work and these plugs are my absolute go to.
Duopower are so good. Use them from the beginning and replaced all other plugs except the special plugs.
When we - Canada - buy the Fischer plugs they come in a kit,so you get screws and plugs.
I would think you would use such fasteners to hang things on walls etc. More of a side load then pulling straight out.
I live in the states and they are sold at the Home Depot screws included. I like them a lot, it's the only drywall anchor I buy currently.
I've been using them a few years and they are amazing but sometimes they dont spread out enough. Also a 6mm sds bit is just fine for them.
Nice one Andy, very interesting...reckon you should have done Shear Tests as well ha ha ........I'm going 😂
Don't start! 😂👍
Fischer-Plugs are the best for my and my house. Fischer-Dübel sind die Bestern für mich und mein Haus. Greets from Germany
Great video! Have you tried fischer's new Powerfast II chipboard screw? It's suitable for use in fischer plugs (eg Duopower and UX) and has recommended loads so you can make the most of the load bearing capacity of the plug. The only screw in the world that can do this!
Fantastic video, thank you
Great video
Agreed that the Fischer Duopower plugs are game-changing. However, care must be taken not to oversize the hole for the plug as the anti-rotation wings are not very large. Suggest using 5.5mm drill to ensure a snug fit in all substrates.
I sometimes drill 1mm undersize in my plasterboard walls with thermalite blocks. It's easy to damage the plasterboard (oversize) leading to a loose fitting. A twist drill gives a cleaner cut and copes with thermalite blocks easily. Over the decades I've used larger and larger plugs - the 1980s rawl plugs pull out eventually. Nothing less than Fisher 8x40 or 10x50 these days.
@@paulhadley9047 Can I ask what diameter screws do you use with the 8x40 and 10x50 plugs? And what series of Fischer plugs are these? They make them in duo power but also UX.
@@lancearmstrong3252 Hi, for strength I always go for the largest diameter recommended for the plug.
If the plug says 6 to 8mm I find 6mm can spin in the nylon, but 8mm is firm.
Length is important, must be slightly longer than plug depth in wall.
For 10x50 I have had good success with long concrete screws from Screwfix. 7.5mm x 100mm.
There is a UX 10x60, with long concrete screws I had a solid support for IKEA support rail for kitchen cabinets. The long screw penetrates the block behind the plug, I mark plug depth with tape on drill.
Interesting as always, thanks Andy. I've been a long time user of the Uno plug because of their versatility in different substrates. They seem comparable to the Uno plug? Better?
Great video, thanks for sharing! At 7:07 you speak about the hammer action of your drill.
When do you (in person) use that? Doing DIY for about 30 years now, I gradually came to the conclusion that I need the hammer action of a drill only
for drilling in concrete or hard natural rock walls (ceilings/floors). For bricks and other light weight construction wall blocks I prefer without.
Maybe it goes a little bit slower but in my eyes the hole keeps better the diameter what was aimed for.
I'd like to hear your opinion on that.
Can you test Rawlplug 4All universal plugs next? I've been pretty impressed with them.
This was exceptionally useful. I was curious if you could say a few words about how the Duopower compare to the UX6 plugs, which as I understand are also quite versatile. However the UX6 do require deeper depth.
i just googled ux6 and i see these are the ones that we get when we install kitchens, they work the best out of any others we used
It'd be interesting to see a Test Tuesday comparing the aerated block to other household objects, such as a loaf of bread, to see which is stronger. I'd put my money on the bread!
From my past experience, different brands of plasterboard can have completely different strengths, even with the same thickness. We used to get our Plasterboard from B&Q as we used to live a couple minute drive from one, but at the new house we have an MKM literally across the road so we decided to get it from there instead and it's a lot stiffer.
Same thickness? Never noticed a huge difference between brands - but yes, aerated blocks. Still beyond me how they support the weight of a house. 😂
@@GosforthHandyman Yep, both 12.5mm
....only if the loaf is stale.. 😏
😎👍☘
You've convinced me to try these in place of my Uno's.
Insane stats though!
I would look for the anomaly in your measuring rig. That's where faults are usually found. If it's no that there is some fault in the method. Like when you see people doing load tests on Hyacinth Buckets old mechanical bathroom scale.
Great video! May I ask a question about the length of Duopower. I have double layer drywall 25mm I guess ..., so what’s the proper length of Duopower I need for my drywall ,? I want to hang a 65 inch TV on that wall..
Very informative video. Could I use the 'push through' method on dot an dab plasterboard (or even battened plasterboard) ie knock the duo plug through to the brickwork or best leave it flush with the plasterboard (longer screws obviously) ?
As far as I know, your tests are the best on CZcams!
Thanks bud! 👍👊
@16:52 Fisher red plug vs. DuoPower - very interesting results
Thanks for the helpful video Should I use a wood screw when putting up heavy ikea floating tv cabinet and ikea floating cabinets with there brackets into brick wall if so do you recommend 6 or 8 mm Fischer plug and does it mater what type of screws I need to use for a tv bracket for a brick wall
Being a clever old bugger [well in my estimation] I was looking for things to comment about, but you covered every single one of them - so you are the clever bugger. As to the previous 300 test result, did you use a 5.5 drill bit, I always used 5.5 bits for red plugs, but there again it has been a long time since I drilled hole in anger.
I am impressed
Another great video. Thanks. Would these also be suitable for dot and dab walls?
Oh yes! Will do a separate vid all about that. 👍
I have a triple plasterboard wall, in which I need to hang 12kg acoustic panels. There is no cavity behind the plasterboard (it has been filled with rockwool). Which fittings would you recommend I use?
I've got the 6 x 30 and 8 x 40mm versions. My findings are as follows in 12.5mm plasterboard. The 6 x 30mm version I'm struggling with. I've tried 4mm and 5mm full threaded screws which were long enough to pierce the end of the plug with item to be fixed in place. What I've found with the 5mm screw is it just turns the complete plug round in the hole once the screw gets around halfway down the plug. With the 4mm screw the plug starts to collapse a little bit which ends up wider than the drilled hole but it certainly doesn't really deform that much which is a similar finding to your video. Now, the 8 x 40mm plug I can get repeatable results which are much better. I've tried both the 4mm and 5mm diameter screws and the plug really deforms a treat, spreading out very well behind the plasterboard. I think I will have to try another kind of small plasterboard plug.
Great stuff! I must admit, although I like the DuoPower as a problem solver, I do prefer the Fischer GP/LDF fixings for lightweight use for the reasons you say - less inclined to rotate. I generally use the expanding metal fixings with a setting tool for heavier stuff. 👍
@@GosforthHandyman Hi, thanks for your reply. I will have to look into the GP/LDF fixing, see what they're all about. Nice videos BTW.
Just to say screw fix cost £6.99. Tool station £3.37 being a woman Screwfix wanted me to buy twisted plasterboard fixings . I declined thanks these work a treat
I want to know how it compares to the standard red plug in plasterboard, and also how it compares to no plugs at all with vertical force. Perhaps also in timber.
I have just sated to use theses plugs and also coming to the same conclusion.
Great video. Did you think the 6x30 plug would be ok for shelf brackets holding books?
you should compare a plug to Tapcon masonry screws.
I really like these, but my only concern is how do they perform if you need to temporarily remove something that is fixed to the wall to redecorate? I haven't yet had to do this but it seems they probably have a reusability of maybe three times before the plug becomes completely chewed up.... then you would need to pull it out of the wall and replace with a new one. Not as issue cost wise, but I can imagine removing the mangled plug from a plasterboard wall creates a bigger hole which likely won't create a tight fit with a fresh duopower plug.
Maybe I'm wrong as I'm only a DIYer, but to me this is the only advantage plasplugs or wall anchors have over these, as rescrewing into them doesn't seem to affect them too badly (and not at all with wall anchors)
I guess you could just fill the hole with some sort of drillable filler (but do those fillers really work?) wait for it to dry, and effectively start over. Otherwise just move everything slightly every time you redecorate 😂
Andy, Toolstation are currently doing the 6 x 30mm Duopower plugs for just £3.75 per hundred .
Wow - that's a great price! 👍
Always worth checking out Tool station, I often find them cheaper for many items.
They arent cheap, but I have to say they are worth their price for the versatility and quality they offer.
How long have the blocks been standing around (curing)? Have noticed big differences between identical blocks of older or recent manufacture. The older being substantially harder.
I'm no diy expert but had to hang a few things around the house the other day,and this video helped me in selecting good plugs to use,I was very impressed with them!! in your vid you mention when drilling the hole to go the depth of the screw?? is this the general approach for all plugs?? always drill to the depth of screw or did it just pertain to these fischer plugs?? cheers!!
They are good for old houses with mixed walls, because they come in huge lengths and perform well. Ordinary plugs are a nightmare in this case.
Good video
Hi great video! How would I apply these results for twin slot shelving uprights. I’m going to be using 65mm duopower plugs with 80 mum screws onto thermalite. Do you think they would hold a weight as it will have multiple fixings along the length? Thanks
A question: if I am later painting a wall with a Fischer Duopower plug installed in the drywall, can the plug be removed (or pushed in deeper) so I can then fill the hole and paint over it?
the fishcher ones have a pretty thick shaft at the hole so if you have crumbling in some walls it prevents them from spinning compared to the regular ones
Hi there,
What size of screws would you recommend for an 8x40mm and a 10x50mm please?
Did that bloke just say "Testes Tuesday" ? …. what a load of bollocks ! … love from Yorkshire again , kisses xxx
Would 6/8 of these work in a double skinned plasterboard wall for hanging a 50” TV ?? Thanks for the video
muy excelente señor taco
Can you test the Toggler Alligator anchors please?
Hi, I have a heavy p[punchbag I want to use. What plugs should I use for it or would you recommend another bolt fixing? The holds on the bracket will fit a M8 screw.
Without going back I'm guessing that 300kg on a red plug was with 5.5mm drill bits. As an apprentice electrician back in the day we always ordered 5.5mm masonry bits to get much better fixings with size 4 woodscrews 👍
Can you do a comparison test between the fisher duopower and the rawl plug uno
Did you compare those with the Duoblade? What is the different use case? Also why plugging tru the wood can be useful?
Thank you.
hi. Thanks for the video. Can you please try Wurth Shark pro? Thanks
Excellent test Andy, any reason why you don't use a pan head self tapping screw?
Just to keep the screw type consistent between tests 👍
