Hex Bolt Part Thread UNF 5/16 x 5-1/2 inch in BZP Grade 5 Steel - ASME B18.2.1 / SAE J429

The most common type of fastener, a hex head bolt is designed to be tightened with a standard spanner or ratchet and socket. Popularly used in all assemblies, a standard hex bolt is a staple across the world. Manufactured to ASME B18. 2.1, and includes an unthreaded 'shoulder' or portion of the shank. A hex drive permits a greater torque load to be applied to the joint over most other drive types.
