Two numbering systems, one washer

Some flat washers appear in the federal record under both an AN960 and a NAS1149 part number. Where both numbers stand under the same stock number, they name the same item and either one gets you the same quote.

Where they do not share a stock number, treat them as different parts. The dash number carries the size and other attributes, and the part page shows the characteristics the record holds for each item.

Questions about flat washers

Is NAS1149 the same as AN960?

Often, but go by the stock number. When an AN960 and a NAS1149 number are listed against one NSN they are the same washer, and the crosswalk table above shows those items. When they are not, treat them as different parts.

Can I order NAS1149 washers by NSN?

Yes. Paste the stock numbers or the full NAS1149 part numbers with quantities; the quote comes back with availability first and pricing on the formal quote.

What should a washer quote request include?

The full part number with its dash number, or the NSN, the quantity for each line, and any approved-manufacturer or origin requirement from the contract.
