1/4 inch UNC Hex Head Bolts ASME B18.2.1 in Bright Zinc Plated (BZP) USA Grade 5 High Tensile Steel

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 section of the shaft. A hex drive permits a greater torque load to be applied to the joint over most other drive types.
