Carriage bolts feature a smooth, dome shaped head, without an external drive for appearance, safety and security. Underneath the head is a square section that is the same diameter as the threaded portion of the bolt, allowing the bolt to be installed with just a single tool. Pre-drilled holes are required for installation.
Carriage bolts are designed to fasten a wooden face to either wood or metal
Zinc finish offers strong corrosion resistance
The head is designed to eliminate the need for a washer
Common applications include security fixings, decking, fencing, furniture, outdoor play equipment; places where the bolt must only be removable from one side
The self-locking square section on the underside of the head pulls into the wooden material as hex nuts are tightened, eliminating spinning after installation
