If the concern is in the accuracy of general torque wrenches then thats another thing. You should always slacken off a torque wrench after use otherwise it will stretch the spring inside and will not be accurate any longer. In the aviation industry torque wrenches are calibrated before every use and the calibration guages are strictly monitored and maintained.
