GENERAL TORQUES
This chart specifies tightening torques for
standard fasteners with a standard ISO
thread pitch. Tightening torque specifica-
tions for special components or assemblies
are provided in applicable sections of this
manual. To avoid warpage, tighten multi-
fastener assemblies in a crisscross fashion
and progressive stages until the specified
tightening torque is reached. Unless other-
wise specified, tightening torque specifica-
tions require clean, dry threads.
Components should be at room tempera-
ture.
