National Aerospace Standard Parts Guide
A National Aerospace Standard (NAS) part is a high-precision aerospace component including high-tensile fasteners, solid rivets, bearings, and structural bushings manufactured to technical specifications set by the Aerospace Industries Association (AIA). If you need to source NAS parts, cross-reference part numbers, or navigate aviation supply chains, this guide breaks down the standard's history, structural capabilities, and official sourcing networks.
What Is a National Aerospace Standard (NAS) Part?
An NAS part is any hardware component or operational practice governed by the National Aerospace Standards library. Maintained by the AIA and accredited by ANSI, the active catalog features over 1,400 active standards designed to ensure structural reliability, extreme heat resistance, and total interchangeability in high-stress engineering environments.
NAS specifications cover critical categories, including:
- High-Strength Fasteners: Precision structural bolts, machine screws, solid rivets, pins, and Lock washer parts.
- Mechanical & Electrical Hardware: Retaining rings, threaded inserts, bushings, clamps, and rod end bearings.
- Operational & Safety Frameworks: Industry specifications like NAS 410 (NDT Personnel Qualification) and FOD (Foreign Object Debris) prevention systems.
Understanding the Standard Evolution: AN vs. MS vs. NAS vs. NASM
Aerospace hardware identifiers have transitioned through several standard series since World War II to keep pace with modern airworthiness demands.

Frequently Asked Questions (FAQs)
What are the main standards used in the aerospace industry?
The primary standards governing aerospace manufacturing are National Aerospace Standards (NAS/NASM), Society of Automotive Engineers (SAE/AS) specifications, Military Standards (MS), and ISO/AS9100 quality management systems.
Who are the big 4 in aerospace?
The "Big 4" prime defense and aerospace contractors typically refer to Boeing, Lockheed Martin, RTX Corporation (formerly Raytheon Technologies), and Northrop Grumman (with Airbus as the primary commercial peer in Europe).
What does NAS mean in aviation?
In aviation hardware and engineering, NAS stands for National Aerospace Standard. It refers to technical specifications maintained by the Aerospace Industries Association (AIA) for high-performance hardware, fasteners, and operational practices.
What are the AS9100 aerospace standards?
AS9100 is the international Quality Management System (QMS) standard for the aviation, space, and defense industries. Based on ISO 9001, it adds aerospace-specific requirements for risk management, supply chain traceability, and counterfeit part prevention.
