How to Determine Correct Working Face

Figures 1 through 4 are intended to help you calculate the working face (F) for various thread rolling applications, determine the angle of chamfer required and position the thread roll properly.

The working face (or F dimension) of the thread roll must always be greater than the length of thread that needs to be generated on the part. The general rule is to allow the thread roll to overhang each end of the blank by at least 1 1⁄4 threads (root to root or crest to crest = 1 thread).

Figure 1 and 3 F = (2.250 x P) + L
Figure 2 and 4 F = (2.500 x P) + L
A = 1.500 x P
B = 1.250 x P H

Whether you’re ordering from our extensive in-stock inventory, or requesting custom-made materials, the thread rolls you get from CJWinter arrive quickly, perform at your exact specs, and last a long, long time.
