NOTE
To determine breakaway torque, thread nut onto 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.
