from what i have read the whole lubing thing does this when you are
worried about proper torque specs. 1) it lowers the coefficient of
friction used in the original torque spec calculation. 2) there is a
chance of hydro-lock there by giving a false torque reading and the chance
that the fastner might come loose as the hydro-lock force bleeds down over
time. this is especially true in blind bore holes, in through holes its
not as big of a problem.
all that said i live in the rust belt and i live by the motto "anti-seize
on every threaded fastner that will ever see water or salt spray". i have
had very few problems with this method in practical reality. in practical
reality the torque spec is void the first time water or salt water gets in
the threads so you can throw most torque specs away after fastners become
exposed. i say that because rust oxide increases torque, thats why rusted
fastners snap. rusted bolts that are "cleaned" have a reduced diameter
and surface area so the torque is not the same, same goes for holes chased
with taps and thread chasers. did i mention that after many years of
wrenching that my hand coupled to a wrench has become a highly accurate
torquing device :).
