APPENDIX H
TORQUE SPECIFICATIONS
H-1.
SCOPE.
This appendix lists standard torque values and provides
general information for applying torque. Special torque
values are indicated in the maintenance procedures for
applicable components.
The torque values listed are for Grade 5 and Grade 8
steel screws, sizes 0.250 through 0.750 in. diameter,
Class 2A thread.
H-2.
GENERAL.
Always use the torque values listed below when the
maintenance procedure does not give a specific torque
value.
Unless otherwise specified, standard torque tolerance
shall be plus or minus 10 percent.
Torque values are based on clean, dry threads. Reduce
torque by 10 percent when engine oil is used as a
lubricant.
Reduce torque by 20 percent if new plated capscrews
are used.
Capscrews threaded into aluminum may require
reductions In torque of 30 percent or more. Capscrews
threaded into aluminum must attain two diameters of
thread engagement.
Table H-1. TORQUE REQUIREMENTS
CAUTION
If replacement capscrews are of a higher grade than
originally supplied, use torque specifications for the
original. This will prevent equipment damage due to
overtorquing.
