I can find no evidence that M8 with 1.5 mm pitch exists - all the
references I have seen mention only 1mm and 1.25 mm pitch in this
size. What are the odds that a set screw of this nature would be of
so uncommon configuration?

A result of a search for M8x1.5 on Google (one of many returns,
BTW).

The die in that photo shows M12x1 RH a standard size.

Of course. A lot of these places use one photo for all of a
generic type of product. (And M12x1 is actually not that standard --
except as the spindle thread on an old Unimat DB-200 or SL-1000. :-)

And note that as a result of the boilerplate that they used, it
also says "THREADS PER INCH" instead of "Thread Pitch (mm)" as it
should. :-)

Try this URL -- for a M6x1 die (a quite standard size):

Or this one (M4x0.5)

Note also that M12x1 is *not* a usually 1" diameter die. Not
enough meat in that diameter.

Here is their M12x1, and it is 1-1/2" diameter.

So -- don't believe the pictures. :-) The ad people who build
the web site don't know what they are talking about. :-)

Enjoy,
