How to calculate lead of thread

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.

The result is a 0.04167 inch thread pitch. To get the thread pitch in millimeters: Multiply 2 inches by 25.4 millimeters per inch to get 50.8 mm. Divide 50.8 mm by 48 threads to obtain a thread pitch of 1.0583 mm.

Lead is the axial advance of a helix or screw during one complete turn (360°) The lead for a screw thread is the axial travel for a single revolution. Pitch is defined as the axial distance between adjacent threads on a helix or screw. In most screws, called "single start" screws, which have a single helical thread along their length, the lead and pitch are equal. They only differ in "mul…
