Hex Head Bolts
Hex Head Bolts are bolt fasteners with a six-sided hexagon head and an externally threaded body. The hexagonal head profile enables easy wrenching while applying enough torque to the bolting joint. Hex bolts are used with hex nuts or a tapped hole. Hexagon head bolts, also known as Hex machine bolts, are other aliases of Hex bolts. The dimensions of hex bolts are defined in both metric and imperial sizes with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN), and ISO metric thread profiles. These bolts are produced across all material categories and ASTM specifications.
