GENERAL TORQUE SPECIFICATIONS/DEFINITION OF UNITS
GENERAL TORQUE
SPECIFICATIONS
This chart specifies torque for standard fasteners
with standard I.S.O. pitch threads. Torque speci-
fications 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 other-
wise specified, torque specifications call for clean,
dry threads. Components should be at room tem-
perature.
A: Distance across flats
