TIGHTENING TORQUES
GENERAL TORQUES
This chart specifies tightening torques for
standard fasteners with a standard ISO
thread pitch. Tightening torque
specifications for special components or
assemblies are provided in applicable
sections of this manual. To avoid warpage,
tighten multifastener assemblies in a
crisscross fashion and progressive stages
until the specified tightening torque is
reached.
Unless otherwise specified, tightening
torque specifications require clean, dry
threads.
Components should be at room
temperature.
