I think we have beaten this poor horse to death. I believe this whole topic started with an Op wanting to know if anyone has installed a cam lock device for the tailstock. I have never attempted this on my Atlas or SB lathes.

He is partially correct. There are two questions:
1) Can it be made to work? He has answered this perfectly. The
thread merely needs to be coarse enough to tighten/loosen
adequately given the available wrench motion.
2) What is the thickness shim required to make it work? This IS
determined by the pitch of the screw. It may well be that sane way
to find the shim thickness is by trial and error. Probably so. But
the thickness that trial and error finds will have been mandated
by the thread pitch and the range of tightness without the shim.
We must be bored out of our skulls today.

Actually, Jim is proving my point! Yes, the thread pitch has to
course enough but whether it is 16tpi, 14tpi, 12tpi doesn't
