Rod screws should only need to be screwed in with reasonable force to keep them in place - not over-torqued or screwed in with a few degrees of a turn to spare or backed out a bit, but screwed in then given a final tighten to lock them. You shouldn't really need Loctite or anything else to prevent a rod screw from backing out as the shoulder by the thread is what keeps the thread in tension in the pillar to secure the screw.
If a rod screw keeps coming undone, then it's either not screwed in tightly enough or isn't screwed in tight as that causes the keys to bind if the threaded pillar isn't lining up properly which puts a slight bend in the rod screw. Also if the screw is bent, it may only be screwed in or backed out to a certain point where the keys no longer bind. In these cases it's a problem that has to be addressed. Another cause of rod screws backing out are bent key barrels which wil grip the rod screw and eventually rotate it enough to cause it to back out, so look for any shiny spots of wear on the rod screw which indicate where it's binding.
