TM 9-6115-664-13&P APPENDIX H TORQUE LIMITS Section I.  INTRODUCTION H-1.  Scope. This   appendix   lists   torque   ratings   for   fasteners   used   on   the   APU.      When   torque   values   are   called   out   in   the maintenance procedures, those torques supersede the torques specified in this appendix.  Table H-1 lists torque limits for standard fasteners installed dry.  Table H-2 provides formulas for converting the dry torque values to wet.  Table H-3 lists torque limits for standard metric fasteners installed dry.
