HARDWARE INFORMATION
The following charts state standard plated
hardware tightening ranges for normal assembly
applications. Decrease the specified torque by
20% when using a thread lubricant. Do not
substitute lower grade hardware for higher grade
hardware. If higher grade hardware than specified
is substituted, tighten only to the specified
hardware torque value to avoid damaging the
threads of the part being threaded into, as when
threading into speed nuts or weldments.
