Hope to build business relationship with you. Hex bolts come in two main varieties: metric hex bolts and ASME hex bolts. These bolts are threaded fasteners with external male threads. While they share similarities with screws, they have distinct characteristics. A hex cap screw is a type of cap screw with a hexagonal head, which is designed to be driven using a wrench (commonly known as a spanner). The key difference between an ASME B18.2.1-compliant hex cap screw and a hex bolt lies in their tolerances, particularly in terms of head height and shank length. This tolerance variation ensures that an ASME B18.2.1 hex cap screw can always be used where a hex bolt is intended, but the reverse might not hold true, as a hex bolt could be slightly oversized for an application requiring a hex cap screw.
