Table 2. Locknut Breakaway Torque Values
NOTE
To determine the breakaway torque, thread the locknut onto screw or bolt until at least two
threads are shown. The locknut shall not make contact with a mating part. Stop the locknut.
The torque necessary to begin turning locknut again is the breakaway torque. Do not reuse
locknuts that do not meet minimum breakaway torque.
