I have seen wires used to captivate bolts. You can also substitute JB Weld for Loctite for a more permanent solution.

So, not sure what your needs are, but there are other useful ways to add anti-rotation to a fastener--like pinning with a cross-holes (dowel pin) for example. Uhh-h-h....maybe even Loctite....depends on what you are doing, materials involved, amount of anti-rotation desired. Spot-weld?
