DEFINITION OF UNITS
This char t 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.
