GENERAL TIGHTENING TORQUE
SPECIFICATIONS
This chart specifies tightening torques for
standard fasteners with a standard ISO thread
pitch. Tightening torque specifications for
special components or assemblies are provi-
ded for each chapter of this manual. To avoid
warpage, tighten multi-fastener assemblies in
a crisscross pattern and progressive stages
until the specified tightening torque is
reached. Unless otherwise specified, tighte-
ning torque specifications require clean, dry
threads. Components should be at room
temperature.
