Is = plain shank (min), Ig = bearing face to the first full thread (max). To the head: full thread up to 3P from the bearing face (not specified by the free sources: ISO 7380-1 value). Listed by one source only, not generated: | = 6, 20, 25.
Conventions
« End: ISO 4753 chamfered end (CH), end face at d1, chamfer at the angle limit.
* Socket: regular hexagon at the modeled s, sharp corners, one corner on +X, flat floor at t.
e Head: flat top dL at k, dome rf down to dk on the collar top, collar dc x c, rounded rims.
« Thread (threaded level): ISO 68-1 basic profile; full thread to Ig, quarter-turn fade toward the head. Threaded to the head: a core at d1 with rt. « Values given only as a limit are modeled at that limit. Features the standard does not dimension are house conventions.
