Is it bad to leave a torque wrench set?

However, when storing a torque wrench for an extended period of time, users should always wind it down to the minimum scale setting and never to zero. A fully loaded torque wrench, left in storage for a long period, can cause a set in the spring, causing it to weaken over time.

Should I zero my torque wrench?

Anyone working in torque will have been taught to wind their torque wrench back to zero after every use. Certainly, if the wrench is wound back at all it should not be adjusted below the minimum scale marking (usually 20% of maximum) – never to zero as this can adversely affect the calibration of the wrench.
