The NAS523 PDF is a detailed document that outlines the technical requirements and recommendations for NAS devices. The specification covers various aspects of NAS design, including:
An aircraft designed in 2024 will reference . An aircraft designed in 1980 likely references NAS523-1981 or -1993 . Do not mix and match revisions unless the engineering change order specifically allows it.
The search for is the first step toward ensuring aerospace-grade quality in your fastener assemblies. This document is more than just a few pages of drawings; it is a safety-critical specification that prevents electrical shorts, insulates against galvanic corrosion, and secures components against vibration failure.

The coding system uses a single cross symbol where information is distributed into four specific quadrants:
The first number following the letters indicates the rivet shank diameter, measured in . 3 = 3/32" diameter 4 = 4/32" (1/8") diameter 5 = 5/32" diameter 6 = 6/32" (3/16") diameter 4. The Length

Usually dictates whether the rivet is a universal head (protruding) or a countersunk head (flush).
The strength of the NAS523 system lies in its ability to pack significant technical data into a short alphanumeric string. A typical code is broken down into specific components that describe the fastener's physical and functional properties. The Symbol
