CATIONS
This chart specifies tightening torques for stan-
dard fasteners with a standard ISO thread
pitch. Tightening torque specifications for spe-
cial components or assemblies are provided for
each chapter of this manual. To avoid warpage,
tighten multi-fastener assemblies in a criss-
cross pattern and progressive stages until the
specified tightening torque is reached. Unless
otherwise specified, tightening torque specifi-
cations require clean, dry threads. Compo-
nents should be at room temperature.
