NAS vs AN Bolts

Aerospace bolts are designed to meet strict guidelines implemented by the Aerospace Industries Association and Army-Navy. 

This includes requirements regarding manufacturing, finishing, tolerances, strength, and material type. 

Despite this, there are a number of different types of bolts and fasteners, which can make it quite overwhelming when purchasing. 

In this post, we will explain the difference between NAS and AN bolts so that you can get a better understanding.

What are NAS bolts?

NAS bolts comply with the National Aerospace Standards Committee’s standards. These standards are updated regularly, with revisions made to make sure that NAS parts provide reliability and high-level performance.

What are AN bolts?

AN bolts are industrial aircraft bolts that are made in accordance with the Air Force-Navy specifications. They are manufactured from zinc-plated or cadmium corrosion-resistant steel, anodized aluminum alloys, and unplated corrosion-resistant steel.

These aircraft bolts can be utilized for both shear and/or ductile applications, and are coded to a certain standard.
