Tri-Rnd Gage

For Measuring Tri-round Thread Rolling Screws

The Tri-Rnd Gage was specifically developed to measure the “C” dimension of TAPTITE screws from sizes #4 through 1/2 inch (M3-M 12). The “C” dimension is the circumscribing circle connecting the three high points on the lobes of TAPTITE screws. This is an important dimension to inspect to be assured of the screw’s proper driving and stripping torque performance. The use of the Tri-Rnd Gage is much easier, faster, and more accurate than the previous gages used in making this measurement. It is ideal for final inspection as well as in-process measuring in the heading and threading operations. The indicator has .0001″ resolution and can be connected to all electronic SPC data collection systems. Gage Repeatability and Reproducibility Study results are 9.5%.
