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