Off Topic - Pitch / Turns

I could use a bit of guidance or confirmation. I am creating a dial index and want to put marks and a few numbers on it. The slide on my devise moves along an M6 x 1 screw. Does that mean that for every one full turn of the screw the slide moves in or out 1 mm, depending on rotation? If so, does the attached image look right?

M6 x 1 means 6mm outside diameter & 1mm thread spacing. So yes, one turn = 1mm axial movement. And the image is correct.

Thanks Henry, I appreciate the confirmation.

you're welcome, Don--but it occurred to me that the dial would be more conventional and easier to read with 50 divisions rather than 40, so each division would be .02mm instead of .025mm.

Thanks again Henry. That would be good too.

I agree! The 8 x .025 divisions seems to come from an 'Imperial' way of thinking (1/8" etc) rather than metric.

Possibly convert 25 mil to inches.
