SPECIFICATIONS
This chart specifies torque for standard fasteners
with standard I.S.O. pitch threads.
Torque specifications for special components or
assemblies are included in the applicable sec-
tions 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.
