Using a Torque Wrench
3-
You don’t have to fully break the handle of the torque wrench to reach the
specified torque; doing so can cause the handle to kick back and loosen
the connection. Any give at all in the handle is sufficient torque.
Do not pivot the wrench handle on your thumb or other fingers, otherwise
you apply an unknown amount of torque to the connection when the
wrench reaches its break point.
Do not twist the head of the wrench relative to the outer conductor mating
plane. If you do, you apply more than the recommended torque.
