pilot-hole
Screw's advance path
A pilot hole is a small hole drilled before inserting a screw or driving a larger drill bit.
The preliminary hole guides the fastener, prevents splitting in wood, and reduces resistance: Always drill a pilot hole when working near the edge of a board.
The term applies literally in construction and woodworking, occasionally extending to preparatory steps in other contexts.
