Cross-Reference
6,859 MS, NAS, AN, AS, mil-spec and OEM part numbers cross-referenced to National Stock Numbers — with published pricing.
Most buyers outside government supply chains don’t search by National Stock Number — they search by the part number on the drawing, the illustrated parts catalog, or the old packaging: an MS, NAS, AN or AS standard hardware number, a mil-spec (M-prefix) reference, or an OEM part number. This lookup cross-references every part number we stock to its NSN, with the same published pricing either way. If you only have an NSN, use the NSN catalog; if you have a drawing but no stock part matches, our U.S.-based CNC machining can make it to print. New to the numbering systems?

Country of origin: Türkiye (Turkey). Turkey is a NATO ally and a normal-trade-relations partner of the United States, and Turkish-origin end items are eligible for a wide range of U.S. federal and DLA procurements.
TAA note: Turkey is not a Trade Agreements Act (TAA) designated country, so these items are generally not eligible for TAA-covered solicitations. They are offerable under the Buy American Act and many non-TAA DLA buys. Buyers are responsible for confirming the origin requirements of their specific solicitation.
Full country-of-origin and source documentation is provided with every order. Fulfillment within 90 days of order. Minimum order may apply.
Items are supplied as stock mil-spec / commercial hardware with source documentation and country-of-origin paperwork on every order. Parts are not supplied with an FAA Form 8130-3 airworthiness tag unless expressly stated on the quote. Buyers installing hardware on certificated aircraft are responsible for acceptance under their own maintenance program, repair station procedures, or owner/operator authority.
