UNF HT Hex Bolt 5/16” GR5

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. 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.
