NAS STANDARD

NAS (National Aerospace Standards) components are meticulously designed to meet stringent aerospace specifications for reliability and precision. Made from materials such as titanium, stainless steel, and alloy steel, NAS components are built to perform under high-stress conditions. Each part is carefully coded and documented to ensure compliance with industry standards. Refer to specification sheets for accurate dimensions and application suitability.

HISTORY

NAS STANDARDS were established in the 1940s by the Aerospace Industries Association (AIA) to meet the growing needs of the U.S. government and military. These standards were vital in creating reliable, interchangeable parts for aircraft, ensuring that components could be used across different platforms without compatibility issues. The system has since become foundational in aerospace part design.
