In the late 1990's our dump truck fleet at our rock quarry had a rash of broken studs on our hub-piloted 22.5 inch wheels. Most happened when removing lug nuts. We began moving our wheel changes in-house, and using a dab of anti-seize on the threads.
We were located about 1.5 miles from the closest pavement, and the threads of the studs were exposed to fine rock dust. We were not able to determine if the damage came from siezed threads or the rock dust jamming the threads when the nuts were removed.
In addition to the anti-seize, we wire-brushed the exposed threads before removing the nuts.
In over ten years, with a fleet of seven trucks and five trailers (most with eight axle combinations) we never had another broken stud. We never had a loose nut, either.
