I believe it may be a 5/8" Whitform thread, I've just had the same problem with the thread on the gearbox output flange nut which I think may be the same size.
If you look on the Tracey Tools website you will see that 5/8" whitform is available in several thread pitches including 16.
Hope this helps, ..... Phil.
