The Aerospace Industries Association, founded in 1919 only a few years after the birth of flight, is the premier trade association representing the nation's major aerospace and defense manufacturers. The Aerospace Industries Association maintains the National Aerospace Standards (NAS). The NAS series is best known for its state-of-the-art, high strength, precision fasteners. In addition to all types of screws, nuts, and rivets, NAS define high pressure hose, electrical connectors, splices and terminations, rod end bearings, and many other types of hardware and components. 3D CAD models of the NAS parts will soon be available in partnership with IHS and PARTsolutions.
