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 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
B: Outside thread diameter
