NOTE
To determine breadway 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 breakway torque. Do not
reuse self-locking nuts that do not meet
minimum breakway torque.
