Why is recalibrating torque wrenches important?

Recalibrating torque wrenches is critical to maintain accuracy in measurements, which is essential for ensuring that fasteners are tightened to the specified torque settings required in aerospace assembly. Torque wrenches are precision instruments used to apply a specific amount of torque to a fastener, and over time, they can become inaccurate due to wear, usage, or environmental factors.

If a torque wrench is not properly calibrated, the torque readings may be incorrect, leading to either under-tightening or over-tightening of fasteners. This can compromise structural integrity and safety in aerospace applications where precision and reliability are paramount. Regular recalibration ensures that the torque wrench is providing the correct torque values, which is vital for maintaining the safety and performance of aircraft components and assemblies.
