APPENDIX A.
TORQUE SPECIFICATION
A.1
Hale General Torque Recommendations
When a specific torque value is NOT specified in a procedure, Hale recommends following the
recommendations in Table 85. Always utilize a minimum of Grade 8 (SAE) or class 10.9 (metric)
for all flange and/or drive line mounting fasteners.
Unless otherwise specified, 1/4-in diameter and larger steel screws are to be SAE grade 5 steel.
Chemical and mechanical properties are to conform to grade 5 per SAE J429.
Unless otherwise specified, steel screws smaller than 1/4-in diameter are to be SAE grade 2
steel. Chemical and mechanical properties are to conform to grade 2 per SAE J429.
Some threaded fasteners used at Hale are treated with a 360° coating of nylon or similar mate-
rial to provide sealing and self-locking properties. Do NOT reuse fasteners with self-locking prop-
erties. This coating conforms to MIL-F-18240, MIL-N-25207, and Industrial Fastener Institute
IFI 124 and IFI 524. The torque value listed in the 360° nylon lock column of the table is added
to the listed torque value for that bolt size. For example, a 5/8–11 SAE grade 5 bolt treated with
360° nylon lock would have a maximum torque value of 150 + 10 = 160 ft-lbs.
