NOTE:

1.These torque values are to be used for all “araware excluding: locknuts, self-tapping screws, thread forming screws, sheet metal screws and socket head setscrews.

2.Recomended seating torque values for locknuts:

a.For prevailing torqix locknuts - use 65% of grade 5 torques.

b.For flange whizlock nuts (and screws) - use 135% of grade 5 torques.

3.Unless otherwise noted on assembly drawings all torque values must meet this specification.
