Thread Size Torque (In.-Lbs.) 10-32 2.0 5/8 - 18 32.0 1/4-28 3 5 3/4-16 50.0 5/16-24 6.5 7/8-14 70.0 3/8-24 9.5 1-12 90.0 7/16-20 14.0 1-1/8-12 117.0 1/2-20 18.0 1-1/4-12 143.0 9/16-18 24.0 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. F-2
