ASTM A490 A325 DIN933 DIN931 4.8 5.8 8.8 10.9 Grade Black Oxide Heavy Hex Head Bolts

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.
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.
