I had the exact same thing with my gfs 722. That bolt they give you is a piece of **** (I mean it's strong, but they don't seem to fit consistently). Had to saw it off and put on one of those long bolts instead. I don't know if chroming it makes it too big or something, but it definitely didn't feel like the right size (hers actually stuck together like yours). just be sure you grease the threads next time if you manage to get it out.
