Hope to build business relationship with you. Hex bolts can be classified into metric and ASME variations. Essentially, bolts are threaded fasteners featuring an external male thread, closely related to and sometimes confused with screws. A hex cap screw, on the other hand, is a fastener with a hexagonal head, designed for wrench (spanner) operation. It's worth noting that an ASME B18.2.1 compliant hex cap screw maintains tighter tolerances for head height and shank length than a hex bolt. This tolerance distinction ensures that an ASME B18.2.1 hex cap screw can consistently replace a hex bolt, while the reverse might not hold true due to potential size differences.
