   Hello All, 
I have a general question.

I have a PDF file I'm re-drawing into CAD form and I show a HOLE with the following dims

1.98 H7. The H7 is upward of the dim, not right next to it. I think it reads a + something and - 0.000

I read that the H7 is a tolerance of 0.0025mm. I had the part made using this dim and the part (2mm Dowel Pin) slides easily in the hole. I measured th Pins and they are all 2mm.

What is H7?

Thanks in Advance.

KenJG
