National Aerospace Standards

FAQs

What is an NAS/NA standard?
“NAS” stands for National Aerospace Standard. The NA prefix is for Metric standards. NAS standards include Part Standards for high strength, precision fasteners.

What is an NASM/NAM standard?
AIA, in coordination with the Department of Defense, has converted over 500 MIL-spec's to NAS. These converted documents carry a “NASM” (for inch based) or “NAM” (for Metric based) prefix. The standard continues to be procured to the MS part number.

How can I participate in the NAS standards process?

Does the AIA NASC manufacture/supply parts?
The Aerospace Industries Association is responsible for developing and maintaining standards for the National Aerospace Standard (NAS) parts, and some Mil-Specs (NASM/NAM) parts. However, we do not supply parts.

Does the NASC keep a list of suppliers?
No, not at this time. AIA works with industry experts to create standards and make them available to the industry, however, we do not qualify suppliers/manufacturers.
