This ACME Thread General Purpose Design Calculator will determine the three classes of General Purpose, 2G, 3G, and 4G, for the external and internal threads. Major Dia. Tolerance class 2G is the preferred class but if less play and backlash is needed, 3G or 4G can be selected. This calculator also can be used to check the self locking capability of …

Tensile Area = Effective Tensile Area (in²) for externally threaded parts.

This application is intended to assist in verifying thread dimensions and applied stresses for ACME screw threads in accordance with ANSI/ASME B1.5-1988. In application, it is suggested that external and internal threads of the same class be used together for
