TM 9-2320-365-34-1 APPENDIX E TORQUE LIMITS E-1.   GENERAL This appendix provides general torque limits for screws and nuts used on the vehicle. Special torque limits are shown in the maintenance procedures for applicable components.   Use the general torque limit given in this appendix when specific torque limits are not given in the maintenance procedure.   These general torque limits can not 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 for a fastener which retains a rubber component, tighten the screw or nut until it touches metal, then tighten one more turn.   Whenever possible, the tightening force (torque) should be applied to the nut side of the fastener group. E-2.   TORQUE LIMITS Refer to Table E-1.  Torque Limits for SAE and ANSI Fasteners for torque limits on standard (SAE and ANSI) screws and free spinning nuts.   Refer to  Table E-2.   Torque Limits for SAE and ANSI Prevailing Torque Nuts  for torque limits on standard (SAE and ANSI) self-locking nuts.  Refer to Table E-3.  Torque Limits for Metric Screws and Free Spinning Nuts  for torque limits on metric screws and free spinning nuts.   Refer to  Table E-4.   Torque Limits for Metric Prevailing Torque Nuts  for torque limits on metric self-locking nuts. E-3.   USE OF TORQUE TABLES (1)  Measure the diameter of the screw to be installed. (2)  Count the number of threads per inch. (3)  Under  the  heading  DIAMETER  look  down  the  column until  the  diameter  of  the  screw  is  found.  (There  are usually two lines beginning with the same diameter.) (4)  Under  the  heading  THREADS  PER  INCH  (SAE  and ANSI)  or  THREAD  PITCH  (metric),  find  the  number  of threads  per  inch  that  matches  the  number  counted  in step (2). (5)  To find the grade of the screw, match the markings on the head to the correct picture under CAPSCREW HEAD MARKINGS on the torque table. (6)  Look down the column under the picture found in step (5)  until  the  torque  limit  (lb-ft  or  N·m)  for  the  diameter and  threads  per  inch  (or  thread  pitch,  in  the  case  of metric fasteners) of the screw are located.
