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 shall 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.

Dry torque limits are used on screws that do not have lubricants applied to threads.
Wet torque limits are used on screws that have high-pressure lubricants applied to

Under the heading SIZE, Iook 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.
