Hex Bolts

Hex Bolts are bolt fasteners with six sided hexagon head and externally threaded body. Hexagonal head profile enables easy wrenching while putting enough torque to the bolting joint.

Hex bolts are used with hex nuts or a tapped hole. Hexagon head bolts, Hex machine bolts are other alias of Hex bolts. Hex bolts dimensions are defined in both metric and imperials sizes with unified national coarse pitch (UNC), fine pitch (UNF), fixed pitch (UN) and iso metric thread profile. These are produced across all material categories and astm specifications.
