I have occasionally seen bolts with a dot of thread lock on them. Any

I think those compounds are uv- or otherwise "set", not just a "dab-on"
application.

Not sure of a specific recommendation, but Permatex and others have a
bundle of options. Whether there's one really adapted that's readily
available I don't know, though.

I'd probably look at something more mechanical if it were mine,
however--peening a thread a little, figuring out how to add a o-ring or
somesuch as a friction washer, etc., ... or, start over w/ a different
flashlight.
