I have seen a video of the nuts having totally failed, just barely clinging to the threads but I can't find it at the moment. I will try to dig it up. The typical solution, like with anti-backlash nuts, is to use brass ones. Delrin is good, at least it is softer than the steel, so it will be the point of failure if it happens.

About two years ago many places offered BZP as a lower cost alternative, but I think most have realized that it was penny-wise and pound-foolish so most now only suggest stainless (or drill rod?).
