GENERAL TORQUE
SPECIFICATIONS
This chart specifies torque for standard fasten-
ers with standard I.S.O. pitch threads. Torque
specifications for special components or
assemblies are provided for each chapter of
this manual. To avoid warpage, tighten multi-
fastener assemblies in a crisscross fashion, in
progressive stages, until the specified torque is
reached. Unless otherwise specified, torque
specifications require clean, dry threads. Com-
ponents should be at room temperature.
A: Distance between flats
B: Outside thread diameter
