GENERAL TIGHTENING TORQUE
SPECIFICATIONS
This chart specifies tightening torques for stan-
dard fasteners with a standard ISO thread pitch.
Tightening torque specifications for special com-
ponents or assemblies are provided for each
chapter of this manual. To avoid warpage, tight-
en multi-fastener assemblies in a crisscross pat-
tern and progressive stages until the specified
tightening torque is reached. Unless otherwise
specified, tightening torque specifications re-
quire clean, dry threads. Components should be
at room temperature.
