GENERAL TIGHTENING TORQUE SPECIFICATIONS/
DEFINITION OF UNITS
This chart specifies tightening torques for
standard fasteners with a standard ISO
thread pitch. Tightening torque specifications
for special components or assemblies are
provided for each chapter of this manual. To
avoid warpage, tighten multi-fastener assem-
blies in a crisscross pattern and progressive
stages until the specified tightening torque is
reached. Unless otherwise specified, tighten-
ing torque specifications require clean, dry
threads. Components should be at room tem-
perature.
