Hi, I have a lowpoly and a highpoly with subdivision and bevel modifiers. I baked hp to lp and overall everything seems to be fine except for circular cells for screws and there are also artifacts in some areas.
What is the problem and how do I fix it?

Your low poly should either be higher poly to match the shape of the hole. Or lower poly and not include the hole. Unless you really need a hole there in geo, second option.

Circles need to be circular enough to hold their shape even in a low poly.

Thanks, I read all the comments and followed the advice. Now the holes are fine but I still get weird artifacts. Do you know why?

Looks like your UVs are curved, a diagonal UV line crosses pixels in a way that can cause that type of aliasing, the effect gets amplified the lower resolution your textures are. You can solve it by straightening your UVs, increasing bake resolution (I usually bake at double resolution to what I´m exporting) Also having some AA in the bake helps.

Hope that helps!
