Micrometer Click Wrenches bring outstanding reliability, accuracy and long life to applications where a click wrench is most convenient. The Micrometer click wrench has precision bearing surfaces which extend the calibrated life of the gage to as many as 60,000 cycles or more and ensures the most reliable performance possible. In addition to precise operation at release, the calibration is completely external, unlike the traditional mechanisms that will require disassembly and the replacement of blocks and shims. Gaging.com carries Precision Instruments brand Torque Wrenches.
