Not really Ed. Looking at it now I'm thinking the best thing to do would be to take the nuts off completely and add set screws that have brass tips to prevent mashing the threads. They would have to be tiny set screws because the nuts are thin. I would just make a single, wider nut with set screws, but the threads on the screw are metric and I don't have the 70T gear I need to make metric threads.
