TM 9-4310-394-13 APPENDIX G TORQUE LIMITS G-1.  GENERAL.  This appendix provides general torque limits for fasteners.  Special torque values are indicated in the maintenance  procedures  for  applicable  components.    The  general  torque  values  given  in  this  appendix  shall  be  used when specific torque values are not indicated in the maintenance procedures. G-2.  TORQUE LIMITS.  Torque limits are listed in Table G-1 for fasteners.  Dry fasteners are defined as fasteners on which   no   lubricants   are   applied   to   the   threads.      Wet   fasteners   are   defined   as   fasteners   on   which   graphite   or molydisulphide  greases  or  other  extreme  pressure  lubricants  are  applied  to  the  threads.    Table  G-2  lists  the  minimum breakaway torque values for locknuts.
