Fully threaded. t = the socket depth modeled (t min, short or long by length). Which lengths are short has one source (LO, #584 item 4).
Conventions
« Socket 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 min.
« Cup point: ISO 4753 CP, an outer chamfer at the angle limit to the axis down to the rim dz (midpoint), and a conical recess at the Figure 1 j) angle from the rim to its apex, a sharp rim. The recess shape is not specified by the standard (#584 item 3).
¢ Thread (threaded level): ISO 68-1 basic profile, the full length, cut by both ends.
« Values given only as a limit are modeled at that limit. Features the standard does not dimension are house conventions.
