Lag Bolt Pilot Hole Size?

Answer

A lag bolt is also referred to as a lag screw. Lag bolts are large wood screws. The size of a typical lag bolt can range in length from 1 inch to 24 inches, or longer. The head of a lag bolt is usually an external hex. In the United Kingdom, lag bolts are known as coach screws. A pilot hole is a small hole drilled into a material before a larger hole is drilled. It is usually done to widen the hole. Pilots holes are also used when driving a screw.
