"Webb13 juni 2024 · Answer: The pitch diameter of an external thread grows by 4 times the thickness of the applied plating. This is because the pitch diameter is measured by contacting 4 flanks on a thread. The plating is applied to all 4 flanks, thus making the effect of the plating 4 times greater than if we measured its thickness on only I surface. " - Pitch diameter for threads
