It is customary in manufacturing to calibrate all measurement devices and the measuring or control systems of tools. This is ensure that the measuring devices and tools are accurate and reliable over time.

Drift in calibration may occur with usage, i.e. normal 'wear and tear'. In the case of a torque wrench, if one frequently uses the wrench at the upper limit of its range, one is more likely to find drift in calibration. Probably in most applications though, drift is not significant, and the routine calibration test is more for quality assurance.

Minor calibrations for wrenches may be necessary due to wear and tear from regular use, exposure to extreme temperatures or environmental factors, and even improper storage or handling. Over time, the internal mechanisms of a torque wrench can become less accurate, leading to inconsistencies in torque measurements. Additionally, if a wrench is dropped or mishandled, it can cause it to go out of range and require recalibration. Regular maintenance and proper usage can help prevent the need for frequent calibrations. It is important to regularly check and calibrate torque wrenches to ensure accurate and precise measurements, which is crucial for safety and efficiency in various industries.
