How often to calibrate a torque wrench?

There are many things to consider when asking how often to calibrate a torque wrench.

• Frequency of use

• The closeness to the maximum capacity the torque wrench is used. For instance if a 300 Nm is always used at 250 Nm or above, it should be more often if it was always used at 30 Nm.

• Has the torque wrench been overloaded by 25% or more

• Conditions in use and storage

• Previous calibration results are key. You should get your torque wrench checked if it is close to the maximum allowed errors. Before your usual calibration frequency.

In general, our answer to how often you should calibrate a torque wrench would be every 12 months. However as you can see from the above list. There are times when this calibration frequency should be reduced.
