ASTM A490 A325 DIN933 DIN931 4.8 5.8 8.8 10.9 Grade  Black Oxide Heavy Hex Head BoltsA bolt is a form of threaded fastener with an external male thread. Bolts are thus closely related to, and often confused with, screws.Â
A hex cap screw is a cap screw with a hexagonal head, designed to be driven by a wrench (spanner). An ASME B18.2.1 compliant cap screw has somewhat tighter tolerances than a hex bolt for the head height and the shank length. The nature of the tolerance difference allows an ASME B18.2.1 hex cap screw to always fit where a hex bolt is installed but a hex bolt could be slightly too large to be used where a hex cap screw is designed in.
