This section provides general torque limits for fasteners.
Torque limits are listed in table E-1 for dry fasteners and in
Special torque values are indicated in the maintenance pro-
table E-2 for wet fasteners. Dry fasteners are defined as
cedures for applicable components. The general torque
fasteners on which no lubricants are applied to the threads;
vaIues given in this appendix shall be used when specific
