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