Use these counter bores create a flat bottomed hole. These special drill bits have a pilot that fits into the already drilled hole. The flutes will widen the hole and create a flat bottom. This flat bottom allows you to have your fastener flush with the surface. These counter bores are designed fillister screws but they should work with your Socket Head screws. You should verify the diameter to make sure.
