Lag Bolts

Lag bolts, lag screws or coach screws, are a heavy duty wood screw with a hexagonal head. They are usually employed in joining timbers or attaching metalwork to timber. Due to their large diameter, and heavy duty nature, a pilot hole is usually predrilled in the timber component. Available in a broad range of sizes and materials for use in projects of varying scale and environments.
