BOOM BOLT NUT

Does anyone know what size and pitch that the lock nut for the bolt that attaches boom to mast.
I found that the Charleston Boom Goose neck nut is M14 but it doesn't refer to Pitch or Coarse Thread.
It seems there are self locking nuts out there that are Coarse Thread and Pitch 2.0 ........... ????
Any feed back would be great.

Cheers
