Hope to build business relationship with you. Hex bolts are categorized into metric hex bolts and ASME hex bolts. Bolts are a type of threaded fastener with an external male thread, often closely associated with and sometimes confused with screws. A hex cap screw is essentially a cap screw featuring a hexagonal head, designed to be turned with a wrench or spanner. ASME B18.2.1 compliant cap screws have slightly stricter tolerances compared to hex bolts, particularly in terms of head height and shank length. This difference in tolerance ensures that an ASME B18.2.1 hex cap screw can always fit in situations where a hex bolt is intended, but a hex bolt might be marginally larger and unsuitable for applications specifically designed for hex cap screws.
