From our discussion of how to use the pitch diameter calculator, we know that we need the values of the basic major diameter and the pitch of the **thread** we are investigating. Knowing those values, we can easily find the basic pitch diameter using this **formula**: d_2 = d - \left (3\times \sqrt {3} \times \frac {P} {8}\right) d2 = d − (3 × 3 ×.

The information below can be used to calculate the values of **thread** tolerances defined by ISO 965/1. Tolerances are written as a combination of a tolerance band, signified by an alphabetic letter, and a tolerance class, signified by a number. For the tolerance band, uppercase letters (E or G) signify internal **threads** whilst lowercase letters (e.
