GENERAL TIGHTENING TORQUE SPECIFI-
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 crisscross pattern and progressive stages 
until the specified tightening torque is reached. 
Unless otherwise specified,...
