5886-G Ring Groove Height Gauge

Ring Groove J-Gauge

Ring Groove Diameter Measurement: Special contact points made of tungsten carbide can be used in conjunction with a #8191 Internal Taper Gauge and a standard vernier to determine groove diameter.

5886-G Ring Groove Height Gauge: Useful on couplings with a ring groove added after threads have been machined. Manufactured with a special anvil and tungsten carbide contact point to measure the thread height relative to the groove bottom. Easily determines depth to .001″

Using several different readings or rotating of the coupling while measuring, will give a reading of grove eccentricity.
