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.
« Flat point: ISO 4753 FL, a chamfer at the angle limit to the axis down to the flat dp (midpoint).
¢ 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.
