TORQUE LIMITS
E-1. SCOPE
This appendix provides general torque limits for the different fasteners used on the ATLAS. Special torque limits are listed 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 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.
E-2. TORQUE LIMITS
Refer to the following tables for specific torque limits:

* Wet torque limits are used on screws that have high pressure lubricants applied to the threads.
** Dry torque limits are used on screws that do not have high pressure lubricants applied to the threads.
E-3. HOW TO USE THE TORQUE TABLE
Measure the diameter of the screw you are installing with
a.
a ruler.
b. Measure out one inch with a ruler and count the number of
threads per inch.
Under the heading SIZE, look down the left-hand
c.
column until you find the diameter of the screw you are installing
(there will usually be two lines beginning with the same size).
d. In the second column under SIZE, find the number of
threads per inch that matches the number of threads per inch you
counted in Step b. (Not required for metric screws.)
e. To find the grade screw you are installing, match the
markings on the head to the correct picture of CAPSCREW
HEAD MARKINGS on the torque table.
