Special application measuring heads produced by Flexbar per customer requirements.
Thread & Ball Screw Thread Measurement
Available in two or three point thread measurement heads according to application
Groove/”O” Ring Groove Measurements
Precise groove measurements are made easily and accurately. Application requirements are groove width minimum of .060” (1.5mm). Groove depth may not exceed half the travel range of the True-Bore head.
Groove/”O” Ring Groove Measurements
Spherical shaped heads are useful in deep bores where holding the bore gage straight in the bore is difficult. The spherical shape allows only a single contact point per anvil on the bore wall.
