Molly plug

[roli]

A picture of how it looks would probably make it easier to understand what's wrong.

The problem is that the entire expander has rotated and damaged the drywall hole instead of the expanding part staying still and expanding when you tighten the screw. I would call it a "common" error when installing your first drywall expanders.

I also recommend using a regular screwdriver instead of a drill until it is completely secure.

Exactly, then you can "feel" more easily if the expander is starting to tend to rotate before it does. With a power drill, it just "spins" and the drywall is ruined, and you end up with an "oversized" hole.

Do what you should have done from the beginning, buy a tång. Then you would have avoided all the trouble.

Would this work?

I bought Jula's version which looks exactly the same. It was completely useless as the "fork" that is supposed to hook and pull the screw head bent after just a few plugs, so it started slipping when you applied pressure.

Instead of buying pliers, I had bought

Drill 10mm holes, insert the plug, and pull out.
Then regular wood screws, hooks, etc. work.

No special tools, works for single and double gypsum.

I have never had any problems when I've tightened manually!

Haha amazon's automatic translation delivers.

It is exactly like the picture I posted in my question.

But isn't that picture from Biltema? I mean a picture of how your Molly looks after you tightened the screw? So that perhaps one can understand why it isn't expanding.

I have noticed that the threads on the screw are deformed at the end (so that it cannot be unscrewed). On some plugs you buy, the screw is pre-screwed so it stays put, so you start by screwing it in a few turns until it turns easily before inserting it into the hole and start tightening.

Sounds like a disadvantage that the screw cannot be unscrewed.

You're thinking in case you were planning to use the Molly to attach something? 😱🙄🙃

 

[useless]

Are you thinking in case someone had intended to use the Mollyn to attach something? 😱🙄🙃

One could imagine regretting it and wanting to unscrew it and fill over the flange that's left.

Yes, it's mostly in that scenario that it can be considered a disadvantage.
