Which wall plug for drywall + wooden board

[SnällKyckling]

Hello

I'm going to hang a very heavy painting with glass, 1x1 meter, and they provided steel wire, noting that I should use it.

A bit worried about the weight since a single screw has to hold everything, what do you recommend and should I use a wall plug? I have drywall and underneath it looks like this (old picture) whatever this is.

In the picture, it's OSB on the left and plywood on the right.
Regardless, you usually just use regular wood screws for such a wall.

Okay, is that what some in the industry call "plyfa"? I need to use a sturdy wood screw, do you have any brand recommendations, or I'm so afraid the picture will fall?

Brand doesn't matter much, but make sure it's a pan head screw, not a countersunk one. Without knowing your exact conditions, maybe a 5 × 30-40 screw could be suitable? If you want to be really secure, you could take a 6 × 40 hex screw.

It's correct that the material on the right is called plyfa!

Brand doesn't matter much, but make sure it is a round-headed screw and not countersunk. Without knowing your exact conditions, perhaps a 5 × 30-40 screw could be suitable? If you want to be really secure, you can take a 6 × 40 hex screw.
