Ive always reused mine too, as long as you can stake it back in jobs a goodun.

Righto. Perhaps. But ... it is good to know that you all seem to reuse the nut! Excellent.

Thanks all.

I re use the nut at least once as I find it goes around a few more mm when correctly tourqued up, so is staked on a fresh part.

FYI, after one fast run I found my hub nut had begun to undo... It´s drilled now, with a split-pin fitted. Job done.
