Everyone praises OSB unanimously for being great to put behind drywall since you can screw into it. I'm doing some woodworking and occasionally use a scrap piece of OSB when building something. Unfortunately, I don't find it particularly good for screwing into. I often find that the threads get stripped when screwing into OSB. What am I doing wrong? Especially 4 mm screws are difficult to get to hold well in OSB.
Osb is not the best for screwing. Plywood is better but also much more expensive. With Osb behind, you have to screw carefully so as not to tear apart the Osb. But it is much better than just drywall. However, if you're going to attach heavy things, I would use kortlivat or plywood. Osb is more for wall lamps, small shelves, picture frames, furniture tip protection, and other small items you want to put up.
As mentioned, OSB cannot be compared with plywood but with the right screw and caution, it serves perfectly well. Choose as coarse a screw as possible and not too long.
If you use a screwdriver, be careful. Even if the torque can be adjusted, it may still be too much even at the lowest setting.

If I plan to hang heavy things behind a wall, I use K-Plyfa, for example, when I built the wall where the TV would hang in the last place, the rest of the wall was with OSB since at most there would be a hook or picture. You can use OSB but just as others say, it’s mostly for small things and makes the walls stiffer and feel less hollow.
Agree. How many constructions are executed with "cheap" OSB behind drywall on metal studs in all the walls?!MathiasS said:I suggest that there's more wrong with your screwing skill than with the OSB board......
I've never had any problems screwing into OSB, whether light or heavy.
After that, everything is hung on it, sinks, shelves, various furnishings, etc... Why would it stop working right now?
I believe it has more to do with screwing skills and wrong screw choices!
Yes, even I think it feels quite unfamiliar that OSB would be bad to screw into.

I have mounted kitchen and heavy shelves and other things in OSB... What you need to consider is the right length of the screw. To screw a metal piece with 1mm thickness onto an OSB/gypsum wall, you need to ensure the threads grip the OSB when it's fully screwed. For example, a 4.2x42mm screw has a fairly long area near the head without threads, so there's a risk that all the threads end up behind the OSB board.
The tensile strength isn't that much worse than plywood!
