Tips on plugs for fire double plasterboard

[Unikt namn]

I wouldn't hang anything on that plug.
The board looks crushed.

I assume you've seen how to mount a molly?

Hi,
I am quite new to plaster walls as we have lived in lightweight concrete houses for half our lives.
I was going to hang a picture weighing 6-7kg, so I got a recommendation for Acrobat (molly?) at the store.

I tried to put it up last night, which went okay after some fiddling; first, the plug spun trying to stay put when tightening the screw, but I had to loosen it to hang the picture, and then it was loose again, eventually eating into the wall and then it sat tightly.
Still, I didn’t dare hang the picture on it after reading your post, so I'm curious why or if it only applied to the OP's purpose?

If you are going to use an expanding plug (Molly), you need an expanding tool to pull out the legs behind the gypsum, then you tighten the screw.

Yes, I followed the instructions. Drilled a hole, used pliers to insert Molly and tighten. It won't pull out but it still sits tight, yet it can spin around.

Yes, I followed the instructions. Drilled a hole, used pliers to insert Molly and tighten. It doesn't seem to pull out but is still secure, yet it can spin around.

I would guess you've either tightened it too loosely or too tightly. It should be rock solid if you've clamped it sufficiently.

I would guess that you have tightened it either too loosely or too tightly. It should be rock solid if you have used the pliers sufficiently.

Sure, unfortunately, I don't know. I tested a Molly outside the wall to see how it worked, and it seemed like you should tighten it with two clicks, which I did. Can't tighten more unless you really force it. So maybe too tight.
Note that if I tighten the screw, then I think it sits really tight, at least it did yesterday, but I have to loosen the screw to hang the picture on it, which makes the whole plug loose.

You'll probably need to turn the tånge 180 degrees because it often pulls slightly askew and that needs to be compensated for. So I usually make at least 3 adjustments. Then the plug is secure and you can use the screw.

 

[J-banan]

Yes, did as instructed. Drilled a hole, used pliers to insert Molly and tighten. It can't be pulled out but it still stays in place, though it does spin around.

There are Molly in different sizes, 1-3 layers of gypsum. Sometimes you need to tighten with pliers 2 times. That is, you screw in the screw after the first tightening and tighten again so that it is secured against the wall properly.

There are Molly bolts in different sizes, 1-3 layers of plasterboard. Sometimes you need to tighten with the pliers twice. That is, you screw in the screw after the first tightening and tighten again so it presses firmly against the wall.

Have double plasterboard according to info, so I bought for double, if that’s not quite right. It's tricky now, I can't even get it out. I’ll stop by Kbygg and see if I can find a longer hook screw to test with the same plug. Do you have any other tips?
Besides tearing down and re-plastering the wall

Have you tightened at least 2 times with the pliers? The cap on the plug is usually easy to remove.

Thanks for the tip, it certainly looks easier to handle.

This is what the plug looks like today, I noticed it's not even secured but you can pull out the plug to what I guess are the wings that have opened.
I used a special tool to get the wings out. Do you even dare to hang the painting on it?

Yes, it looks normal when using a molly plug. If you pull slightly off-angle, or too little, the plug won't hold. You might also have problems if you've drilled a hole for the plug right next to a stud.

Since the painting will cover the mess, and you say the plug holds when you tighten it, you can unscrew the screw, put on a reasonably large washer and a nut about 5mm under the screw head (just so the picture wire fits), screw back the screw so that the washer and nut clamp the plug, and then hang the painting on the part of the screw that now sticks out beyond the washer/screw. The washer prevents the plug from sliding into the hole if it's become a bit large.

Yes, it looks like it usually does when using mollyplugs. If you drill at a slight angle, or not enough, the plug won't hold. There can also be issues if you've drilled a hole for the plug right next to a stud.

Since the painting will cover the mess, and you say the plug holds when you tighten it, you can unscrew the screw, put on a fairly large washer and a nut about 5mm below the screw head (just so the picture wire can fit), screw the screw back in so that the washer and nut clamp the plug, and then hang the painting on the part of the screw that now sticks out beyond the washer/screw. The washer prevents the plug from going into the hole if it's become a bit too large.

is it possible to use the hook you suggested through the plug?

 

[Thomas59]

Can you use the hook you suggested through the plug?

Yes, if you find a small hook/hanger that fits, it works fine. Then you can skip the nut, but you might still need the washer so the plug stays better if the hook doesn't cover the hole with margin. A quick Google search for "picture hooks" brought this up, see image. You might need to drill out the hole in the hook depending on the diameter of the molly screw. So it becomes: wall-molly-washer-hook-screw

Drilled out the plug now and inserted a Hercules hook as you suggested earlier.
It seems to hold on if the hook doesn't bend now, in the same large hole that was used for the plug originally.

It seems to hold as the hook isn't bending now, in the same big hole that was there for the plug from the start.

Thomas59, I am eternally grateful to you. That Hercules hook you recommended is truly fantastic
I've hung up the painting with it and now a heavy mirror. Drill with the smallest drill bit and insert it into the wall super easily

Nice to be able to help. Unfortunately, the standard advice at consumer hardware stores is Molly plug, which is often the least suitable fastener, creates ugly holes in the wall, difficult to remove, and tricky to apply if you don't have the technique/Molly pliers. Have a nice weekend.
