If you want to get really technical, here is the ISRI site for metal specifications. I think the #2 pencil lead guideline is also from ISRI and used by many scrap yards.

If you want to get really technical, the "#2" refers to the hardness of the pencil lead, not its thickness. (And yeah, it's not lead either, it's graphite.)
