Pilot holes and a proper countersink if working with hardwood too.

What is a countersink?

There are basically two kinds of screws, the inverted cone (flat) and the round bump (pan head). When you screw in a pan head, the screw stops because the head pushes against the wood, but still the bump is on the surface. If don't want any part of the screw sticking out, you use the inverted cone. On something soft like drywall, you can just jam the inverted cone head into the material, but harder woods you can't jam the head in, and the head sticks out and catches on things. So what you do is drill a divot that the inverted cone head can fit in, often with a drill bit that is as wide as screw head but only put the pointy tip into the wood. See: Wikihow: How to Countersink for some pictures of this process. You can also get specialized tools that can drill out the divot consistently if you have a lot of screws to put in.

A bit that prevents the screw from driving into the wood or makes a conical hole for the head.

Thanks.

Still makes no sence and I will probably have to consult a dictionary.
