Yup! +/- .003 accuracy
No need.Get a digital caliper - One that will toggle between mm/inches/fractions and be done. lol
I'm gonna further split hairs here and say the pic was taken at slight angle, hence what appears as 1.8665ish is actually close to 1.8667ish.Not a machinist, but I read that as 1.8665 inches or 47.41 mm
Is that NY DN or AR DN ?I have done a lot of quality work over the years, working with drawings, specifications etc. There is a new geometric symbol being used on drawings now. It was issued by the SAE early this year. So I just want to make every one aware of this addition. It is a tolerance symbol where as the dimension must be right on, with out deviation, perfect, got it. It's called " Dead Nuts " See attached.

I can’t begin to tell you how many times over my career I had a customer ask me “tolerance?” “Can’t you just make it perfect?” My reply was always “sure I can, but each move of the decimal point to the left increases the cost by a factor of 10. How close do you want it?”I have done a lot of quality work over the years, working with drawings, specifications etc. There is a new geometric symbol being used on drawings now.
