STUB ACME THREAD CALCULATOR

When created prior to 1895, Acme screw threads were intended to replace square threads and a variety of threads of other forms used chiefly for the purpose of traversing motion on machines, tools, etc. Acme screw threads are now extensively used for a variety of purposes. Long-length Acme threads are used for controlled movements on machine tools, testing machines, jacks, aircraft flaps, and conveyors. Short-length threads are used on valve stems, hose connectors, bonnets on pressure cylinders, steering mechanisms, and camera lens movements.

For basic Acme thread dimensions see our dimensional charts.

To use this calculator enter your Thread Major Diameter and TPI, then select your Class and Modified Form.
