Dave , I just "found" the little set screws you were talking about , I doubt very much if they will fail and make the ring go out of the setting . You probably could replace them with a metal set screw but this could mess up the part behind it . I personally would not worry about it , they used nylon on the set I bought in 2013 and never had an issue.
