NOTE
To determine breakaway torque, thread into screw or bolt until at
least two threads stick out. Nut shall not make contact with a mating
part. Stop the nut. Torque necessary to begin turning nut again is the
breakaway torque. Do not reuse self-locking nuts that do not meet
minimum breakaway torque.
