China Supplier ASTM A325 A490 B7 B8 stainless steel Heavy Hex Bolt/Hex head bolt
A 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.
