Thread file for fork nut

[Chris]

Hi anyone know which threadfile I should buy ? One of my Landsdowne alloy nuts has rolled up on undoing it. I've run a new steel fork nut down the stantion & it's fine.
Thanks

As an aside, I use black moly grease to give those threads a fighting chance in life.

If you have a 7/16" or 1/2" UNF (both 20 TPI) tap then you can use it as a thread chaser.

I usually make do with any triangular file I find in my tool box.

Thanks Lab something I have to hand.
Slick usually do this cleaning up steel bolts but the alloy has rolled making it hard to see the pitch.
Concours never greased them before? Will try that .
