NOTES

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

2.Recommended seating torque values for locknuts:

a.for prevailing torque 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.
