248 looks like its designed to hold something heavy

As I stated in a previous post, I should have mentioned this one is a
close-up, six time larger than actual size.

251 is a screw, probobly designed to have a lot of grip/holding power.

Yes, for drywall

252 looks like some kind of clamp

Correct, though not very specific...
