i have found if you use just a tiny bit of anti-seize, galled threads are prevented. just a guess here, but i think the galling comes from the difference in the plating [or lack there of] differences between the studs and nuts. and to be clear, i torque my nuts to 85-100lbft. depending on the wheels being used and the nut type [cone or shank seat], and have no issues with them coming loose.
