**Pitch Diameter Formula | Math Problems Solving …**
In this table find the Class 2G, Pitch Diameter, Maximum and Minimum limiting diameters for the 1.250-5 ACME-2G thread. You should find that the table gives you 1.1210 as the minimum size and 1.1410 as the maximum size for the pitch diameter calculation. We will use the median dimension of 1.1310 for our formula calculation. Now that we have all of the information, let's plug the numbers into the formula.

**>formula For Calulating Unified Thread Pitch Tolerance**
29/06/2014 · The formula on top of Table 4 on Pages 56-57 cites a three part equation where the product thread nominal diameter, pitch, and length of engagement are treated as separate components for Class 2A. The tolerance is then factored up or down to suit each class of thread for external (A - male) or internal (B - female) and to determine allowance for Class 2A and Class 3A.

The thread series is generally relative to the outside diameter of the screw. 20 threads per inch on a 1/4" diameter screw is considered coarse: 1/4-20 UNC. On a 3/4" diameter screw, 20 threads per inch is considered extra-fine: 3/4-20 UNEF. It also plays a role in determining the length of engagement.
