Proto Torque Calibration

Torque calibration is an important part of any torque tool job. The last thing you want is an inaccurate calibration. This could result in ruining the piece you're trying to tighten or having a piece that is too loose, which can cause parts to damage over time. Proto Torque Calibration tools are made to have extremely accurate measures that help you to rely on your torque tools with less worries. Proto Torque Calibration tools have a number of features to help make them easier to use and provide accuracy other torque calibration tools just can't provide.
