GENERAL TIGHTENING TORQUE
SPECIFICATIONS
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 war-
page, tighten multi-fastener assemblies in a
crisscross pattern and progressive stages until
the specified tightening torque is reached. Un-
less otherwise specified, tightening torque
specifications require clean, dry threads. Com-
ponents should be at room temperature.
