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.

ANSI Hardware Engineering DataInternal ACME Thread General Purpose Size Chart. The following table defines recommended industry standard sizes for External ACME General Purpose Threads per American National Standard ASME/ANSI B1.5. There are three classes of General Purpose ACME threads, 2G, 3G, and 4G each class provides some clearance on all standard size diameters for free movement, and are used in assemblies with the internal thread rigidly fixed and movement of the external thread in a ...

ANSI Standard Hardware Menu. ASME/ANSI B1.8-1988 (R2001) provides for the Stub Acme screw thread for those unusual applications where, due to mechanical or metallurgical considerations, a coarse pitch thread of shallow depth is required. The fit of Stub Acme threads corresponds to the Class 2G General Purpose Acme thread in American National Standard ANSI B1.5-1988.

Typical applications are vises and jack screw applications. They have wide trapezoidal thread crests that make motion possible. ACME thread pitches are measured ...
