General tightening torque
This chart indicates the tightening torques for
standard fasteners with a standard ISO
thread pitch. Tightening torque specifications
for special components and assemblies are
provided in the applicable sections of this
manual. To prevent warpage, tighten multi-
fastener assemblies in a crisscross fashion
and progressive stages until the specified
torque is reached. Unless otherwise indi-
cated, torque specifications require clean, dry
threads.
Components should be at room temperature.
