Now I have some parts machined to the nominal dimension that have been returned by the customer for rework. Believe me when I say that I wont make that mistake again.

Of course the meaning is not affected, but this has been the custom so I would say that everyone should stick with that convention. Thanks for your comment!

But it seems that the zero is always there for metric tolerances. Is this a rule? I notice that sometimes, with inch tolerances, there is no zero in front of the decimal point.
