GENERAL TORQUE SPECIFICATIONS
This chart specifies torque for standard fasteners with
standard I.S.O. pitch threads. Torque specifications for
special components or assemblies are included in the
applicable sections of this book. To avoid warpage,
tighten multi-fastener assemblies in a crisscross fashion,
in progressive stages, until full torque is reached. Unless
otherwise specified, torque specifications call for clean,
dry threads. Components should be at room temperature.
