- Want to know how strong drywall fixings are? My 'go to' wall plug for very lightweight items in plasterboard are these little Fischer GP drywall fixings. They're only recommended for loads up to 2kg but I wanted to see what they can actually withstand. In this Test Tuesday video I'm going to test for axial and shear loads to see if there's much difference. There are LOADS of lightweight fixings out there - these ones are great for pictures, light mirrors etc.

SORRY FOLKS! My bad, peak load was actually 14.25kg... I think! Missed that. Going to do this test again with the new rig so watch this space.
i know im asking randomly but does anyone know of a method to log back into an instagram account..?
I somehow lost the account password. I would appreciate any tips you can give me
@Javier Ariel instablaster :)
@Lawson Andy I really appreciate your reply. I found the site on google and Im waiting for the hacking stuff atm.
Looks like it's gonna take quite some time so I will get back to you later when my account password hopefully is recovered.
@Lawson Andy It did the trick and I finally got access to my account again. I'm so happy:D
Thanks so much, you saved my ass!
@Javier Ariel You are welcome =)
I was planning to use these for a speaker bracket but was worried they would not hold. The speaker weights 4Kg and after seeing this I feel confident that the bracket with 4 of these fittings will be just fine. Thank for you for the great and informative video.
Informative and fun! Really like your "test tuesday" videos.
Cheers Mark! 👍🛠
Loving these tests Andy!
Cheers Jim! 👍
Very interesting test. Since we have no drywalls at home I've never used these kind of fixings.
Our house is entirely drywall 😂
Already when you bought/rented it? Or during/just before moving in?
I know some people who have dry walls in front of their (kind of) brick (outer) walls which were very uneven.
To make it stronger, they put at first a layer of OSB and after that the "real" dry walls (gypsum board)
Bought that way (new build) - most new builds here are plasterboard over block (dot & dab) or plasterboard over studs. 👍
That's interesting to know. Thanks.
Love this series.
Cheers Andy! 👍😀
To be fair, the fastener and anchor combo did not fail. The substrate material ‘drywall’ yielded as one would expect. However, your test numbers in both axial and shear force yields should be consistent within a range of anchors of this diameter. I am curious if other brand anchor testing vids reveals this. Larger diameter anchors should spread the load out, maybe ? Since drywall is so common, and people hang the weirdest stuff from their walls, a fun destructive test would be how much could one actually hang from a wall using anchors commonly available, regardless of diameter. Maybe test best method or pattern vs quantity etc, ( without stud penetration). I’m sounding crazy, but destructive testing is a great topic and your series appears very popular. Thanks for your effort on the videos, great material. New subscriber. Safe New Year to you !
Welcome to the channel! 👍
I think Fisher driver fixings are good for general plaster board fixings. Iam surprised with these though stronger than I thought they would be
👍🛠
Good test, really good to see these real world tests. I don't suppose you'd be interested in testing the Fischer UX6 and UX8 plugs? They're my go to, find them great but sadly they're a single use.
Cheers,
Dan
I quite like the Fischer Duopower ones too - will add to the list! 👍
It’d be interesting to see anchor resin and threaded bolt in a thermalite. There isn’t much that’ll get a good fixing in lightweight blocks
Wall bolts coming soon. 👍
Its the plasterboard that will fail first with most fixings, just saying. Keep up the good work, like all your vids. I am getting more into things now I have finished work. Screwfix regular visitor.
👍🛠
Maybe you could try the plastic self drilling plasterboard and see how they hold up, in my experience they hold a lot more than the grey plugs. The ones they sell in Poundland are basically holding everything up in my house. I put a swinging TV bracket up with them and you can literally hang on it when it's swung out. But then again, it depends on what thickness of plasterboard you have, 12.5mm is a hell of a lot stronger than the 9.5m plasterboard
On the list - although I've seen a lot of disasters with these I'm afraid! 👍😃
Great video, thanks. Very informative.
Cheers Mark! 👍🛠
An interesting test. It would useful to see a test with a realistic item, such as a cabinet, fixed to the dry wall and see how much load it will take.
I wouldn't use these for cabinets - only for very light loads. 👍🛠
Thank you for the info think you are the uk of Matthias Wandel love it THANKS
Unfortunately they both seem to have the same arm problems.
Thank you Joseph - very kind! He's way ahead of my on the testing jigs 😀. Does Matthias have arm problems too?
According his latest video, I'd say yes.

Oh no! Dropped him a note but lots of comments on his vid so he may not see it.
whoop for test tuesday!! i must have 20 kilo vision... because whenever i so much as **look** at one of those shitty drywall anchors, they fall out of the wall! ;) those anchors took more weight than i thought they would though.... but ever since i learned about molly bolts from you (srsly, they're so buried under the shelves in my local hardware stores i never saw them...thanks Andy) that's almost exclusively what i use when i can't find a stud.
Yeah, these are only for pictures, light mirrors etc. Only rated to 2kg. 👍🛠
What screws are you using?
I use an awl to make the hole for my plugs. I wonder if compressing the material in the board instead of removing it for the hole makes a difference.
I'm using them to attach a bog roll holder today.
Top stuff sir 👍
whats the green tool on the end of the screw driver?
It's a Wera Rapidaptor - it locks the bit in the holder and has a free spinning outer you can hold on to

May I ask you a ? I have a lot of wood screws, various lengths etc. I want some general-purpose screws for jobs like this as I've just bought 100 of these fixings following your website link. I guess I am just in need of more screws for jobs other than wood. I was putting a hook up yesterday and all I had was wood screws. Can you advise me what to look for and the sizes I need (I'd like to have a good selection in stock for various jobs, so the most used) thank you
Made up of from which type of plastic?
Ever try fischers plastic expanding plasterboard anchors? Same principle as the metal ones but made of plastic?
Um... not sure to be honest! Can you post a link? 👍
The ones I meant seem to be discontinued. They used to be sold both as fischer and in kits with ELFA/Sparring wardrobe fittings. I think the current style is the Fischer PD 8-12. Ages ago when I worked in a DIY store they used to be colot coded blue and red for 10 and 12 and behaved roughly like the metal anchors but no special tools required. These days most new houses here in sweden will have OSB or construction plywood behind the plaster board though so plugs and anchors are not as much of an issue.
Omg this test is awful!!!! Why have you included a test jig that supports the plasterboard 50mm ish around the fixing? Try the test in real world situations where you have just 400mm of drywall or plasterboard to support your load between joists.
Tried with and without that support (see later videos) but same results. 👍
@@GosforthHandyman TBH I posted this comment with a few bevvies in me. The idea is the same but my conveyance could have been a little less rude , sorry.
Would it be correct in thinking that if one can withstand say 20kg. Then if you were mounting a TV and you had 4 or 6 of these plugs that each one plug is only supporting 5kg or 3kgs and a bit?
Yes BUT never go by the peak load - you must always cater for a safety factor - normally 3-4 times smaller at least. Always go by the manufacturer recommended ratings - I think for these it's 5kg per fixing, so I wouldn't use these for a TV.
@@GosforthHandyman what sort would you recommend I watched your vid with the corefix ones but where my TV would go there wouldn't be any brick work behind. It's backed by the stair case? It's a new build so can't even check for studs ect just yet... Help needed 👍🏼
Hey Jimmy - I really can't advise without seeing it in person. For a 20kg on a flat-to-wall bracket I'd probably use expanding metal anchors on a hollow wall but if it's a cantilever bracket you'd need to hit the studs. 👍
@@GosforthHandyman OK mate that's great, thanks for the advice, appreciate it. Keep up the vids, all best 👍🏼
Or, expanding foam/gorilla glue with water sprayed on substrate and without water sprayed on
Now we know what the weight may be on a single plug. But say you use 6 to 9 plugs to hang a shelf and place a heavy object like an old tv or microwave,or something over 15/20kg. I wonder if it would eventually pull out over time. In a real world application many of these would be used to hang a heavy object,distributing the pull weight on many plugs.
You would definitely NOT use these little plugs for heavy stuff like that. See other vids e.g. expanding metal anchors. 👍
@@GosforthHandyman Yup I know that. Just got me thinking if one little plug takes that amount of kg,I wonder what would happen if kg was spread out over many plugs. Thx for the reply. Have a good 👍 day.
Try also using the latest Duck Foot anchor: www.ebay.co.uk/itm/DUCK-FOOT-PLASTERBOARD-FIXINGS-M5-x-70mm-ANCHOR-DRYWALL-CAVITY-FIX/192817678206?epid=16029372551&hash=item2ce4d4477e:g:iBYAAOSwxlxcXB1f
We call it plasterboard in the UK. ;D
I know - gets less hits though. 😂
Rawlplug Uno are my favourites. I use them for almost everything indoor and out - red for lightweight, brown for heavy, and blue for when someone has already drilled a hole too big...
They're good - used them too. 👍
SureGrips are better! 😁😁
Hi. What is your opinion of the Fischer Duopower and Duotec plugs please? I installed a TV bracket on plasterboard with anchors (used a setting tool) so it ain't coming down :) However, the Duopower and Duotec (in particular) look quite good.
The Duotec will double us as normal plug if the cavity is too small for gravity for it to 'open up' behind the plasterboard.
Would appreciate your take please mate. Ta muchly
Duotec look great - got a box ready for testing! 👍
@@GosforthHandyman Luckily I have subscribed and tapped the bell so I will know when you have put them through their paces 😜
Good test there, mate. 👍
I think those types of plugs are a go to for most people hanging lightweight things.
👍👍
They’re very good wee fixings, I’ve been using them for a long time but I wouldn’t hang a coat rail with them unless I found at least one stud. Great video thank you Andy. Do a test by putting the GoPro in the vice and see how long it takes to crush it 👍😄
GoPro - it would have to make it past the end of my boot first! 😂😂
Looking forward to seeing more test vids. I use Spit Redidrivas for that sort of thing. Would love to see a Concrete screw test.
Do you mean the sort that don't need a plug? 👍
They are a metal plug that screws in to the plasterboard with a supplied screw that goes into that.
Page 39 in the Screwfix book ☺
Ah sorry it been a long day! Concrete screws, yes no plug screws into the block/concrete. A mate swears by them I'm still using Frame fixings.
I wonder if some of the pull out was due to the screw not being fully threaded? Would be good to see it done with a fully threaded screw. It would be also be interesting if having a screw with a more defined thread would make a difference, maybe a turbo gold, I guess you’ve used a silver screw there. Great channel, keep up the good work.
Could well be - d'oh! I'm so used to using those screws for putting battening up I didn't even look - my bad! Turbogold are a bit aggressive to use in plugs IMHO since the serrated shank removes a fair bit of the plastic. They work but I prefer Quicksilver / Silver / Goldscrews for plugs if poss. Cheers bud! 👍
Time to construct a full-on test jig Andy!👍👍👍👍👍👍👍👍
It's already evolving! 😂
I don't like to use very lightweight fittings, I tend to use the two screw type with an outer alloy hollow screw and an inner screw to hold the fixture.
The self drilling ones? Watch this space. 👍😀
Gosforth Handyman that's the ones.
Nice one Andy. Another good demo of just how good these fixings are if you use them properly.
A suggestion for a test would be to see if there is much difference if someone was to fit them wrong. Say someone forced them into a 5mm hole or into a 7mm hole. The type of thing a rookie DIYer would do and think it was fine cos it worked once :)
Cheers - good idea! A smaller hole would probably get better or similar results. 👍
Mmmm,,this seemed To go on forever and ever 😩😩😩😩
Lol... I'll do a little dance next time?? 😂😂
