ididit and borgeson and flaming river all dont recommend doing that, the nut wont come off, but the clearance in the u joint to the shaft and the clearances in the hole you drill to the bolt will all allow the shaft to wiggle just a little bit, minutely at first, eventually it will wear and wiggle more. drilling through one side if its a hollow shaft, or drilling a small detent if its a solid shaft, forces the tube to one side of the u joint and locks it in place, no wiggle. even without loctite the set screw wont loosen if you tighten the lock bolt.
