Iffin you REALLY wanted to be sure that a nut won't fall off a screw, or a
screw will loosen, wouldn't plain ole 2-part epoxy be the best bet?

Also, if an epoxied screw/nut did have to come off, wouldn't a little heat
do it?

If you really want to be sure, hit it with an arc welder.

Prevailing torque nuts do the job extremely well (stovers). And
drilling and safety wiring them is just icing on the cake.
