Striper28,
I use mostly 1x72 screws in socket head, pan head, and flathead (countersunk), 82 degree
Socket head diameter is about .115 in diameter and .070 high. The pan head are .134 in diameter but only .040 high. They work great for thinner scales. The flathead are.160 in diameter and .060 high, on an 82 degree angle.
I get these screws from Les Halpern.
