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.
