IFLAT WASHERS IMS-AN-NAS-ASTM

More than one outside diameter (00)may exist for the same size of flat washers. For popularstandard sizes, wedonotinclude the 00 in ourpart number. For special OD's, use the fourth sectionof ourpart number, asshown below.

For example:

For MS-AN-NAS items, Star uses the official MS-AN-NAS part number, not the regular partnumber for the size that we are accustomed to.
