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.
