Collection: Aerospace Standard

Aerospace Standard (AS) Hardware, O-Rings & Seals

Aerospace Standard (AS) components support modern aviation and aerospace maintenance with specification-driven hardware and sealing solutions. This collection includes precision aircraft hardware—bolts, nuts, washers, and fasteners—along with commonly used O-rings and seals for hydraulic, fuel, oil, and pneumatic applications. AS standards were developed to modernize and, in many cases, succeed legacy AN specifications by refining engineering requirements and performance criteria.

Products in this collection are sourced from qualified manufacturers and supplied to Aerospace Standard specifications. Manufacturers may vary depending on availability, but all items meet the required dimensional and material standards for their specifications. Material certifications are available upon request to support traceability, inspection documentation, and shop compliance needs.
