WebHow to Calculate Lead Angle The Lead Angle is calculated based on the following formula: where l is the lead, d is effective diameter, n is the number of thread starts, and P is the pitch. Since the lead angle is unitless, the chosen units for dimensions don't matter as long as they are consistent. WebIn order to calculate the lead error effect on the functional diameter for all threads types, use the following formula: Functional Diameter Change = (2 x lead error) / TAN(included angle/2) Ex. (2 x 0.001”) / TAN (60/2) = (0.002”) / TAN (30) = 0.003464” So, a 0.001” lead error will affect the functional diameter 0.0035” for this example.
