NAS Washers

NAS fasteners, including NAS-certified washers, meet the strict technical standards required in the aerospace industry. NAS washers are used for high-performance applications, including aircraft and spacecraft component manufacturing and other critical industrial uses. NAS washers are available in multiple material and coating options for superior strength and corrosion resistance.

What Does It Mean For Washers to Meet National Aerospace Standards?

National Aerospace Standards (NAS) are technical standards developed and maintained by the Aerospace Industries Association (AIA) in the United States. These standards cover a range of aerospace components, including washers. When a washer is NAS-certified, it meets the specific requirements outlined in the applicable NAS standard. For example, NAS620 is a widely-used standard that covers flat washers for use in aircraft, missiles, and other aerospace applications. The NAS620 standard outlines requirements for the washer's material, dimensions, finish, and other characteristics.
