In all the years of using these things, I've never had one loosen up on me. How does that happen? I mean, it hangs to the side, it swings up, hangs back to the side, swings up, over and over. Where does all the twisting happen that causes these things to get so loose? I just don't get it I guess.
In my case I was removing it when I needed to put the tripod mount on. I've since gone to a manfrotto mount with the custom fastenR and that stays on forever but I was always leery that I was going to loosen the bolt by continuing to swap between the mounts.
