Plug come loose from drywall, how to reattach?

[huggan]

As mentioned, it's now a 10 mm hole and I want to screw in a small shelf. No heavy weights, but how do I do it?

Tried with drywall anchors but they just spin around and the hollow wall anchor's screw is too short to reach.

Any good solution?

Considered drywall compound and then drywall anchors again.

maybe a molly?

It's the same as a cavity plug, but the screw is too short and the hardware store didn't have longer screws.

Plaster expander then?

It's the same, isn't it???

But they are regular M-threaded screws. How long do you need them?

What kind of hardware store doesn't have regular screws?

Too short screw with expanded molly? It's usually M-thread on them, so you should be able to find a screw, right? Have you used pliers for the molly?

Otherwise, I would have tried cleaning the hole of loose drywall, vacuuming it. Put in a molly with PL400 on the wings and squeeze it with a molly plier. Wait until it has dried and buy a longer screw (if necessary).

It is an m6 screw and I need one that is 110mm long.

strange that you need such a long screw.
but they are usually available at a hardware store. otherwise, you could use gängstång

or maybe a disc plug PD with a screw

It's because the screw has to go through the wood, which means it doesn't reach the thread in the molly/gypsum expander/hollow wall plug. I searched online but no one sold longer than 90mm. The wife brought home a gängstång but I'm not sure how nice it will look. I thought you guys here on the forum might have some clever solutions.

from 16mm to 150mm

surely you have expanded the cavity plug? because wasn't it metal molly?

 

[huggan]

Yes, I have. Otherwise, I would have needed even longer.

I am not interested in carriage bolts.
