APPENDIX C
TORQUE VALUES FOR THREADED FASTENERS
C-1. GENERAL
This section provides general torque limits for screws used on the M992A1 vehicle. Special torque limits are indicated
in the maintenance procedures for applicable components.
The general torque limits given in this appendix will be
used when specific torque limits are not indicated in the maintenance procedure.
These general torque limits cannot
be applied to screws that retain rubber components; the rubber components will be damaged before the correct torque
limit is reached. If a special torque limit is not given in the maintenance instructions, tighten the screw or nut until it
touches the metal bracket, then tighten it one more turn.
C-2. TORQUE LIMITS.
Table C-1 (p. C-2) lists dry torque limits. Dry torque limits are used on screws that do not have lubricants applied to
threads. Table C-2 (p. C-3) lists wet torque limits.
Wet torque limits are used on screws that have high-pressure
lubricants applied to threads.
C-3. HOW TO USE TORQUE TABLE.
1.
2.
3.
4.
Measure the diameter of the screw to be installed.
Count the number of threads per inch or use a pitch gage.
Under the heading SIZE, look down the left-hand column until the diameter of screw to be installed is found
(there will usually be two lines beginning with the same size).
In the second column under SIZE, find the number of threads per inch that matches the number of threads
counted in step 2.
