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?

Nylon insert nuts or deformed locking nut will do it, if you ever have
to get it apart. A nut with a check nut will work as well. Could
drill and wire, too. Castle nut with a cotter pin works for car hubs.
If you NEVER have to remove the fastener, just rivet the joint.

Threadlockers are really meant for bolts or studs going into tapped
holes, there are nuts designed for locking duty, see above. Epoxies
really suck at holding shear forces, which is what you get with a nut
unscrewing.
