Rob, et al,
ARP fasteners say, I think, that for accurate torque, we should lubricate the threads in a cleaned environment. Be sure to lubricate under the head of the bolt if it is a cap screw.
I think that the engine builders on the assembly line just use the as-machined threads and hardware, with residual cutting oil and assembly lube on the threads and don't pay attention to the underside of cap screws.
So, what is the correct way? And what happens to torque when Loctite is used? That means clean threads.
Or does it make a particle of difference?
Thanks for your kind response.
