GENERAL TORQUE
SPECIFICATIONS
This chart specifies torque for standard fas-
teners with standard I.S.O. pitch threads.
Torque specifications for special compo-
nents 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.
A: Distance across flats
