(Volker Borchert) fired this volley in
news:mo6j31 :

WTF is this? It's obviously neither M12(x1,75) nor UNC1/2x13...
Is there an UNC15/32x13? Or even a cross-over 12mmx13TPI?

How did you determine the threads per inch?

14mm x 2mm pitch is very close to 13tpi, and the tap drill size of
15/32 works well.

Sorry... your 'footnotes' didn't appear on my screen until after I'd
posted and scrolled down further... duh!

I dunno!
