CONVERSION TABLE
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
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. Com-
ponents should be at room temperature.
A: Distance between flats
B: Outside thread diameter
