DEFINITION OF UNITS
GENERAL TORQUE
SPECIFICATIONS
This chart specifies torque for standard fasteners
with standard I.S.O. pitch threads. Torque specifi-
cations for special components or assemblies are
included in the applicable sections of this book.
To avoid warpage, tighten multi-fastener assem-
blies 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 tem-
perature.
