External general purpose ACME Thread size table chart 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 direction perpendicular to its axis limited by its bearing or bearings. 5,V.e2KKSTI&\KYS-nl1T'aie.a#%:=%.%.,R7 Straight pipe setting plug gages Calibrate and set a straight pipe thread ring.
