Fastening in beadboard on drywall

[Ronny68]

Hello!

I have purchased 2x of these:

I hung them up with the included plugs and screws, but one of the four screws has already failed.

I was thinking of using Molly, but behind the tongue and groove paneling, there is an air gap, and then gypsum, which exceeds 26mm, the intended depth for the Molly I have.

What type of plug should I use? Are there other fastening alternatives?

Thank you very much in advance!

If you have wood beadboard, you should not use plugs, only wood screws.
Then one might wonder how sturdy the beadboard is? It doesn't show in the pictures.

there is trippelmolly that can handle 40 mm

If you have wooden beadboard, you shouldn't use plugs, just wood screws. Then you might wonder how sturdy the beadboard is? Not visible in the pictures.

This is what the wall looks like, but it doesn't say anything about what's behind it. When I drilled the hole, I first went through the beadboard (wood), then there was a cavity and then drywall. I assume the beadboard is mounted on a crossbeam or something? It should be stable then? Any specific wood screws to recommend?

Thanks!

choose a wood screw about 5 mm thick and a length that is at least 5 mm longer than the beadboard and what you are fastening together. Do not make it longer if it is additionally longer.

If the head of the screw is visible, choose one that you think suits the appearance. It entirely depends on how what you are fastening looks, I think. If there are countersunk holes, choose a wood screw with a countersunk head. Otherwise, a flat head or mounting screw.

choose wood screws about 5 mm thick and a length so that it is at least 5 mm longer than the beadboard and what you are fastening together. Do not make it longer than that.

If the screw head is visible, choose one that you think fits aesthetically. It completely depends on what you're attaching, I think. If there are countersunk holes, use a wood screw with a countersunk head. Otherwise, a flat head or installation screw.

I have already drilled 8mm holes for the plugs that were/are there now. Is it a good idea to buy 10mm and screw into the 8mm holes?

10 mm screw? Sounds extreme. And screws that thick are usually quite long.

Can't you move the shelf a couple of cm to the side and thus hide the holes?

Yes, I can do that, was just being lazy

Is there a risk of the tongue cracking so that I should pre-drill?

 

[Tosse]

Absolutely, do it! The drill should be slightly smaller than the inner diameter (inside the threads) of the screw. For a 5 mm screw, it should not be more than 2.5-3 mm.

Is it possible that the space between the panel and the gypsum has been used to run electricity? Try to find out how the electricity is routed so you don't accidentally drill directly into an electrical conduit.
