STARRETT ACME SCREW THREAD PITCH GAGESTARRETT ACME SCREW THREAD PITCH GAGE 51319, STEEL GAGE, ACME STANDARD SCREW THREAD This gage is a standard for grinding and setting tools when cutting Acme Threads. Acme Threads have the same depth as square threads but the sides of the threads are at an inclination of 14-1/2-Degrees (29-Degree included angle).The advantage of the Acme Thread are its strength and the ease by which it can be compared with square threads. In use, the angle on the thread cutting tool is checked on the large precision ground V at the end of the gage. The tool is then ground on the end to the width of the slot of whatever pitch is being turned. It is then set in the lathe using the half angle.
