The pitch diameter (often called the effective diameter) of a parallel thread is the diameter of the imaginary co-axial cylinder which intersects the surface of the thread in such a manner that the intercept on a generator of the cylinder, between the points where it meets the opposite flanks of a thread groove, is equal to half the nominal pitch of ...
Each H limit represents 0.0005 inches over basic pitch diameter. The best way to visualize the differences in screw thread classes of fit is shown on the bar graph in Figure 2. This example shows the pitch diameter limits for Â¼-28 UNF internal and external standard threads.
