Ahhh .......... not a common metric thread then ......  :hammer: ........... mmmmmmmmmm ..............  grinding up a hss bit might be the way to go ..... but ........  that's way outside my comfort zone so I'll defer to the more experienced on here  :bow:

Hallo.
Living in the "metric" world,I can second that a regular M12x2 thread does not exist.

The chart shows coarse or regular on the left,fine metric sizes on the right

Darren:
Neither does 10x2, but I have a tap for one..... :)

Darren:
Eric, I can find 12x3 but not 12x2

Are you sure the application calls for 12x2?
