    I don't know if I have posted this before but:

    To any of you who have lost Bach or Benge or Holton stop rod nuts, the threads is 5-40 which is non-standard. A very good replacement for these nuts is available at your local hardware store. Buy one nylon 4-40 nut and carefully split it along its length with a box cutter or similar. It will now thread onto the stop rod and be so tight that it cannot possibly vibrate off. You only need one.

    Ivan, I would assume to issues with hard throws from the slide popping it loose?

    The nylon nut will not spring off - other things will break before it lets go.

    The other easy solution is to replace the rod with a standard 4/40 machine screw of suitable length and use a locking nut. It is after all just a allan key that is required to remove the original rod............ Cutting the head off of a screw and filing it smooth is not that tough. I have never even noticed a change in the sound............ ;-)
