																	NOTES
			1/2			Body						1. These torque values are to be used for all hardware
						Length						excluding: locknuts, self-tapping screws, thread forming
		3/4										screws, sheet metal screws and socket head setscrews.
												2. Recommended seating torque values for locknuts:
				3								a.	for prevailing torque locknuts - use 65% of grade 5
		1/4											torques.
												b.	for flange whizlock nuts and screws - use 135% of
			1/2										grade 5 torques.
												3. Unless otherwise noted on assembly drawings, all torque
		3/4		4								values must meet this specification.
