General Tightening Torque Specs
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 warping 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.
