Phil01 What a load of ****, Bob carry on using coppaslip, I use it as well on my studs and been doing it in the motor trade for umpteen years and never had a nut come loose due to incorrect torque, and at least you know the nut will undo at the side of the road when its pissing down with rain doing a wheel change

Friction on the stud has nothing to do with it, it is the final clamping force that is what is reqd
Im not trying to force or preach to anyone to change habits even If I think it is right or wrong.
Just people should be aware that lubricated studs or nuts will result in an over stretched stud or bolt compared to a dry stud or bolt for the same torque figure.
Phil how is the torque achieved. . What does the nut or bolt actually act against once it contacted the mounting face.. the threads, so if lubricated the force (torque) required to further turn the nut bolt is less. More turns more stretch, we don't measure clamping force, if we did then its all moot.
If you see what I mean?
I work all day with critical torques some down to a 0.10% tolerance . The differences in stretch between lubed and non lubed can be measured.
Anyway said my bit so have a nice sunny day in your part of the world where ever that may be.

Actually the stud/nut is not that critical unless you are a baboon, it can be anywhere from the force of a woman using the supplied wheel nut wrench with such a low leverage ratio right up to a monster idiot using a breaker bar.
You too Rob, have a great day mate
