This chart specifies torque for standard fasteners
with standard I.S.O. pitch threads. Torque

assemblies are included in the applicable sections
of this book. To avoid warpage, tighten multi-
fastener assemblies in a crisscross fashion, in pro-

otherwise specified, torque specifications call for
clean, dry threads. Components should be at
room temperature.
