Hillman 3/8-in x 1-in Zinc-Plated Coarse Thread Hex Bolt

Hex bolts are machine bolts designed to fasten facing pieces of wood and/or metal
The zinc plating is rust resistant and provides a beautiful, consistent finish, but may not work for all exterior projects
Pre-drill a pilot hole the same diameter as the hex bolt you are using
Commonly used in home and commercial projects involving wood-to-wood and wood-to-metal connections
Partially threaded shank allows for a stronger grip between objects and less shear movement
