For example, the thickness of the coating of the thread crest is thicker than the median diameter and the bottom of the tooth, and the thickness of the plating at both ends of the screw and the bolt is thicker than the middle, and is more remarkable as the length to diameter ratio increases.

Due to the shielding effect during the nut plating process, the thickness of the plating layer on the internal thread is very thin, and only the first fastener on both ends is thicker than the plating in the middle portion, which is equivalent to the hex wrench surface. thickness.
