. If you break the head off, you are stuck. Plus the head design is completely wrong. But use whatever works for you
In the real world, drywall screws get used for hundreds of purposes besides hanging drywall. Not saying it's right, just a fact of life. I've done a lot of remodeling and have found (and in a pinch occasionally used) them in places you probably wouldn't approve of.
Favorite trick is to use a drywall screw when you need to hold a piece of base or crown molding away from a wavy or out of square wall a little bit to close up a joint. Sink a drywall screw into the wall behind the molding to create a stop, then adjust it in or out to close the gap and nail off the molding.
I also hang pictures with them...should I be concerned the heads will snap off and my pricelesss

lol

art collection will come crashing to the ground?
OP I've found quite a few switches and receptacles installed in plastic boxes with drywall screws. Cover plates fit just fine.
Ask a question like that and the answers will range from "just run a drywall screw into the wallowed out hole, put the plate back on and go have a beer" to Oh, f*ck, it's unsafe, you need to re-wire the entire house, get out while you still can."
