Pitch Diameter
Pitch Diameter is the basic dimension of a screw, threaded hole, or a tap the diameter of an imaginary cylinder, the surface of which passes through the thread where width of thread and space between threads are identical. This cylinder, of course, would be a cone for tapered taps. It is upon Pitch Diameter that tolerance limits are based to establish Class of Thread.
