To add to some other confusion..
With regard to aftermarket high quality fasteners i.e. ARP or other.... my
understanding is that they may have a coating (anti rust or other?) on them
from the factory.
I have been told that the clamping force and torque specs are different if
the fastener has a coating & lubricant vs. uncoated & lubricant vs. coated &
dry or lastly dry and uncoated.
Since different manufacturers use different fastener coatings...I have been
told to wire brush the threads clean of any coating prior to application and
place them dry in our old design motors.
