Crown Bolt 5/16 in.-18 tpi x 3/4 in. Zinc-Plated Hex Bolt

These hex bolts have hexagonal heads and are for general purpose applications with a socket type installation tool or standard wrench. The standard bolt is compatible with standard nuts and washers of the same thread pitch, grade, and finish. An alternative for using hex bolts without nuts is to place them directly into a compatible female threaded receptacle. They require a pre drilled whole or pre-tapped hole with compatible female thread. Available in various materials, grades, and finishes.
