¢ Thread over the whole length, right hand: a plain 1:16 cone at the simplified level, the 55° profile at the threaded level. No run-out. « 45° chamfer to the thread root at both ends: not specified by the standard, the large end's illustrative.
« Socket: sharp corners, flat floor at t1, no countersink. Not specified by the standard.
« No markings. Features the standard does not dimension are house conventions.
