SPEC
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.
