Hi Jon
A die is the best solution but if you had a lathe you could use a thread chaser or if the lathe boasted screw cutting facilities just clean the thread directly in the lathe (with a suitably sharpened cutting tool).
My lathe is very old, relatively cheap but I’ve used it to cut and clean threads. Notably to make a pinion flange locknut. I seem to remember that that was 20 t.p.i Whitworth form.
Cheers
Howard
