   en.wikipedia.org/wiki/List_of_screw_and_bolt_types

   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. Fine ...

   Dimensions of heavy hex geometry are per document ANSI/ASME B18.2.6, which uses "coarse" threads as defined by Unified Thread Standard. ASTM 325 bolts can be considered equivalent to Grade 8.8 bolts according to ASTM F568M. [citation needed] For a higher strength version of this type of bolt, see ASTM A490.

   Bolt (fastener) Threaded fastener with an external male thread requiring a matching female thread. Bolt with a nut. A bolt is an externally helical threaded fastener capable of being tightened or released by a twisting force (torque) to a matching nut. The bolt has an external male thread requiring a matching nut with a pre-formed female thread.
