National Aerospace Standards (NAS) – Fasteners & Hardware
National Aerospace Standards (NAS) are precision aerospace and defense fastener specifications established and maintained by the Aerospace Industries Association (AIA). NAS standards define strict requirements for high-performance bolts, screws, nuts, washers, rivets, pins, and other hardware used across commercial aircraft, military platforms, spacecraft, and other critical applications where strength, interchangeability, and reliability are essential. NAS fasteners meet demanding industry quality expectations for aerospace OEM, military specification (Mil-Spec), and high-stress engineering environments.
AIAP is your resource for NAS parts with over 8,000 part numbers in stock.
