What is the favorite screw for wall mounting? (Plaster + hardboard)

[Stampen]

The new summer house is now complete and the mounting frenzy begins: hat racks, roller blinds, TVs - everything needs to go up on the walls.

The house is consistently built with 13 mm plasterboard + 12 mm hardboard, so the question is which screws do you prefer for things that don't require molly screws? I'm thinking of buying a bunch of 3-4 x 30-40 mm to avoid debating whether the included screw is adequate or not.

A follow-up question - are there stud finders that can detect studs behind hardboard or is it wishful thinking to believe that it would work?

Wood screws that go through particle board (I assume that's what you mean by 12mm masonite?) hold for most things you mention. Rounded head is often suitable.

Yes, it's particle board of course. So the question is which wood screw is preferred 3 mm, 4 mm and should it be 30 mm in length or is it better with 40 to accommodate for things that add more to the front, etc.?

I have mostly used 40 and 4mm, but 4 can be a bit coarse sometimes depending on what is being set up, so 3 can be good to have with you.

Thanks, that's kind of what I was thinking, buying 4x40 and 3x30 so you have both sizes on hand depending on what's being mounted. If you're lucky and find a stud, then it's not bad to have the 4x40 for better grip.

How about stud finders, are you out of luck behind particle board, or can you find them that way?

Thanks, that's kind of what I was thinking, buying 4x40 and 3x30 so you have both models on hand depending on what needs to be installed. If you're lucky, you'll find a stud, and then it's not a bad idea to have 4x40 that grips a bit.

How about stud finders, is it hopeless behind chipboard or can you find them that way?

Though if you're going to attach to a stud, feel free to go up to 50-60

But if you are going to set a rule, feel free to go up to 50-60

However, few things require a rule if you have chipboard behind.

But if you are going to mount into the stud, feel free to go up to 50-60

a bit like that, I assume I won't hit a stud, and if it turns out to be a stud, then 40 mm in gypsum+chipboard+stud is better than just gypsum and chipboard, but sure, if it's something heavy, you can switch to a longer one, the one the manufacturer provided, etc.
