When you build a strut, use an impact wrench. You'd be surprised to see that the nut moves when the strut rod doesn't by virtue of how an impact wrench works.

Get a thread chaser for that size and just run it up and down the damaged section next time you need to remove the nut or install the nut. Also yes, chamfering the threads way from the flats is fine as that's NOT where the nut needs to engage threads to hold torque.
