What does "UNO" stand for? This is on a metric drawing and applies to a set of holes. I Can't find this out on web?? I used to know in another life. I think it is a DIN standard? Any help appreciated even direction to correct thread/forum.

RE: uno

It might help to post a picture of the example. Also as this is in part a drafting question you might try the Drafting Standards, GD&T & Tolerance Analysis forum.

Yes, please give us a picture.  Needs to be seen in context.

Good on ya,

RE: uno

"Unless Noted Otherwise" if that makes sense in the context. Also seen it as UON for "Unless Otherwise Noted."

Egg on face but knew it was simple, a draftsman thing!

Thanks!!

RE: uno

eBook - Mastering Tolerances for Machined Parts
When making CNC machined parts, mastering tolerances can be challenging. Are general tolerances good enough? When does it make sense to call out for tighter tolerances? Do you need a better understanding of fits, datums, or GD&T? Learn about these topics and more in Xometry's new e-book. Download Now
eBook – How to Choose the Correct Corrosion Testing Method
When designing a metal component, engineers have to consider how susceptible certain alloys are to corrosion in the final product’s operating environment. In a recent study by NACE (National Association of Corrosion Engineers), it was estimated that the direct and indirect costs of corrosion in the United States is approximately 6.2% of the GDP. In 2016, that cost exceeded $1 trillion dollars for the first time. Download Now
