what does 'reduces the required torqueby 40 % , in the case of
anti-seize' really mean?
doe that mean if one uses anti-sieze and then torques to 120 ft lbs
...the actual reading will be .......?
or ....
does that mean it's handy to use anti-seize so the nuts and bolts don't
have to be so tight ..
or what ?
what does that actually mean 'reduces the required torque' ?
sounds like a good thing stated that way.
