Wow - talk about luck - maybe you should go buy a lottery ticket too, lol??!!

Blue loctite works for me - did you give it enough time to set up? If you apply and use immed, its pretty much like its not there. I try to give it several hrs to cure. Other thing, I always clean both pieces with some motor spray - if there is the least bit of oil or grease, loctite won't set.

I also keep a few spare nuts around just in case. Mine are not Ofna, but HBs and the nuts are avaliable. I'd be surprised if Ofnas were not.
