Track-bike nuts as a replacement for flange nuts?

[Afrozoolander]

I have a single-speed bicycle that I love very much. However, I have noticed that the flange nuts on the horizontal dropouts might be eating away at the frame.

Can I use track-bike nuts instead? It is an irrational fear of mine that the rear wheels will slip out of the horizontal dropouts during a descent.

Furthermore, I am having trouble acquiring these. I can't seem to find any online. Do you think that a local bike store would have these? Please recommend where I can purchase them.

Track bike nuts should/ might have a fine threads. Maybe @Loose cogcan advise as i know my Dura-Ace hubs are fine threads.

Yo Yo Yo .... try a set of washers between the nut and drop out to protect the frame.

With a horizontal drop out, as long as your chain stays on and your axel is not on the end / tips of the drop out, then there is no way that the wheel will slide out off the back of the dropouts.

Take the wheel with you when you go looking, not all threads are the same. Axle threads in particular.
