Hello Wilfred
To the best of my knowledge the thread is a non standard 5/8 x 16 Whitform so not BSF. If you have the correct tap it should clean out the thread of a hardened crank.
However, I have had a Phoenix crank in the past that had an under size thread in the nose. I had to screwcut the starter dog under size to get it to fit.
Hope that helps.
Adrian.
