GENERAL TORQUE
SPECIFICATIONS
This chart specifies torque for standard fasten-
ers with standard I.S.O. pitch threads. Torque
specifications for special components or as-
semblies 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 specifica-
tions call for clean, dry threads. Components
should be at room temperature.
