How should torque wrenches be stored for optimal longevity?

Storing torque wrenches at their lowest settings is the recommended practice for optimal longevity. When a torque wrench is maintained at its lowest torque setting, it helps to relieve tension on the internal spring mechanism. This is crucial because keeping the wrench at higher settings can cause unnecessary stress and can lead to calibration drift over time. By storing it at a lower setting, you minimize wear and tear, thereby extending the lifespan of the tool and maintaining its accuracy for future use.

Other storage methods, like keeping them in padded cases or hanging on a wall, might protect the wrench from physical damage but do not address the critical aspect of tension on the internal components. Thus, adjusting the torque setting to its lowest point before storage is the most effective way to ensure the wrench remains precise and functional.
