Using a Torque Wrench

Set or Seizure

Should this set or seizing take place, it is necessary to break the set by rotating the nut or bolt in a back-off direction, and again apply tightening movement with the torque wrench by a steady sweep of the wrench, during which time the torque reading should be taken.

This procedure is necessary since it has been found that a torque reading taken from a seized or starting position of the fastener is usually greater than the torque to which the fastener was originally tightened.
