I agree with Gene T & Sea Fever, the old bolts no doubt took a beating. I have used blue Locktite for many years on many different applications and can't remember any fittings that came loose when Locltite was properly applied. Never had any problems taking things apart with it although some times a little extra pressure was needed to start un-screwing things, but, IIRC, never snapped any bolts off. Short of safety wiring, which requires drilling the bolt heads in addition to cramped quarters, the only other things I can think of are really aggressive lock washers, which with blue Locktite should do the job.
Also, the Locktite may help prevent rust from forming on the threads. No affiliation with Locktite, just a long time satisfied user.
