how do you use hamer drive hollow screws?

Question

i put them in the wall but i cant get them to stay tight .
their is no studs in the wall

Answer 1

Before installing, make sure that the screw is all the way in. They are meant to be hammered in, but that can make quite a mess of the wall, both inside and outside the wall which is probably the reason you are not having good luck tightening them. I have found that by drilling a hole one drill size smaller than the diameter of the screw and then banging in until the teeth are in the wall is a better method.

Answer 2

Get some plastic inserts that go into wall first. when you put in screws, they flare out and hold tight, or use molly bolts
