Basic Pitch Diameter
Pitch diameter varies with the number of threads per inch because the number of threads of pitch screw determines the height of thread.
Since Basic pitch diameter is measured from points half the height of the fully formed thread, a hole drilled to provide theoretical 50% thread engagement would be of the same diameter as the pitch diameter of the top.
