When are torque wrenches typically recalibrated?

Torque wrenches are essential tools for achieving the precise torque specifications needed in various assembly tasks, especially in aviation maintenance. The proper functioning of a torque wrench is critical, as an inaccurate torque reading can lead to improper assembly and potentially hazardous conditions.

Recalibrating torque wrenches at scheduled intervals ensures that they maintain their accuracy over time due to regular wear and tear, usage, and potential external factors that may affect their calibration. Additionally, if a torque wrench is dropped or mistreated—such as being exposed to extreme temperatures or heavy impacts—it can lose its calibration and provide inaccurate torque readings. Therefore, it is necessary to recalibrate under these circumstances to ensure ongoing reliability and safety.

While it might seem sufficient to only recalibrate annually or after every use, maintaining the integrity and precision of the tool requires a more balanced approach that includes regular checks as well as immediate recalibration after misuse. This ensures that every application of the torque wrench meets the required standards without risking safety or performance.
