Click-type torque wrenches, which use a calibrated clutch mechanism, should always be stored with the gauge dial set at its lowest setting. This preserves calibration of the tool the longest. Avoid using a torque wrench for initial assembly or for disassembly to maximize calibration longevity. Tighten to final torque setting with a slow, steady motion. Once the tool clicks to signal it has reached the selected torque setting, release tension on the tool immediately.
