GENERAL TORQUE SPECIFICATIONS
This chart specifies torque for standard fasteners
with standard I.S.O. pitch threads. Torque specifi-
cations for special components or assemblies are
provided for each chapter of this manual. To avoid
warpage, tighten multi-fastener assemblies in a
crisscross fashion, in progressive stages, until the
specified torque is reached. Unless otherwise
specified, torque specifications require clean, dry
threads. Components should be at room tempera-
ture.
