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 provided 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,
tightening torque specifications require clean, dry threads. Components should be at room
temperature.
