Hope to build business relationship with you. Hex bolts come in two main categories: metric hex bolts and ASME hex bolts. These fasteners feature external male threads and are often confused with screws due to their threaded nature. Hex cap screws, with their hexagonal heads, are designed for wrench-driven installation. ASME B18.2.1-compliant hex cap screws have tighter tolerances for head height and shank length compared to hex bolts. This difference in tolerance ensures that ASME B18.2.1 hex cap screws fit where hex bolts are installed, but the reverse might not be true, as hex bolts may be slightly larger for hex cap screw applications.
