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

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.
