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.
