Pilot hole is defined as which of the following?

• A. A small hole drilled as a guide for the insertion of a nail or screw, or for the drilling of a larger hole.
• B. A hole used to trap moisture.
• C. A hole that weakens the workpiece.
• D. A hole with no function.

Answer: (A)

Pilot holes are small holes drilled to guide the insertion of a nail or screw, or to guide the drilling of a larger hole. This helps the screw go in straight and reduces the risk of the workpiece splitting, while also making it easier to drill an accurate larger hole. The other ideas don’t fit because a pilot hole isn’t about trapping moisture, weakening the piece, or having no function—the point is to provide guidance and precision in fastening or drilling.
