Hillman 1/4-in x 8-in Zinc-plated Coarse Thread Interior Carriage Bolt 100 -Count

Carriage bolts are designed to fasten a wooden face to either wood or metal

The zinc plating is rust resistant and provides a beautiful, consistent finish, but, may not work for all exterior projects

Install by pushing the carriage bolt through a pre-drilled hole, secure placement with hex nuts and washers

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
