The rule I was taught was 2 sizes up if it is a pilot hole. I think that would amount to 7/16ths. But this also can depend on the material you are driving into. If it is more delicate and prone to splitting (in the case of wood) you might want to only go up 1 size then.

∙ 11y agoI (and most people ) don't normally make holes for wood screws. You want them to bite into the wood. However if you insist you need a hole, a 3/32 hole would allow this screw to bite slightly, or a 5/64 hole would give it clearance.

What does it mean to countersink a screw?
to counter sink the screw means the screw head should lay under the wood surface-- the head should not stick up past the surface of the wood to do this I use my drill with a Phillips head bit and bore a hole in the wood while swirling my wrist and pushing down to widen the hole a bit-- this makes the head hole a bit larger and allows the screw head to sink below the wood surface without creating any wood splintering around the top of the hole by over forcing the screw
What is Countersinking?
Countersinking is the drilling of part of the metal/wood, so as to allow an ordinary countersink screw head to lie flush with the surface. The angle of the head of a countersunk screw differs from the angle of a standard drill. So one should use a special countersink drill for the job. It is not proper to prepare the hole, for a countersunk head, by using a standard metal drill.
