WebThis ACME Thread General Purpose Design Calculator will determine the three classes of General Purpose, 2G, 3G, and 4G, for the external and internal threads. In application, it is suggested that external and internal threads of the same class be used together for general purpose assemblies, Class 2G being the preferred choice. WebThe profile angle β and the lead angle π determine the geometrical shape of the thread. The lead angle of a thread can be derived from the following formula: Tan α = P / d2 x π . The size of the flank angle determines the intended use of the thread. Fastening threads have a larger point angle, motion threads a smaller point angle.
