Calibration is the process of verifying and adjusting the accuracy of a torque wrench. Performing torque wrench calibration is very important because it ensures that the tool is measuring torque accurately and consistently. And precision and accuracy are critical to the safety and quality of the end product.

Over time, torque wrenches can become less accurate due to wear and tear or other factors, such as exposure to extreme temperatures or humidity. If a torque wrench is not calibrated regularly, it may give inaccurate readings, and this can result in safety hazards, product failures, or costly repairs.
