Provides load-bearing limits for each specified code during structural modifications. How to Find Official PDFs
The NAS523 rivet code PDF is essential for several reasons:
On aerospace blueprints, the NAS523 code is frequently presented as a cross (quadrant symbol). Each quadrant of the cross contains specific information about the fastener's characteristics and installation requirements.
This upper-left quadrant contains a letter code that identifies the specific rivet part number (e.g., AN or MS series) and the material alloy. nas523 rivet code pdf
The final number indicates the length of the rivet shank, measured in . -4 = 4/16" (or 1/4") length -6 = 6/16" (or 3/8") length -8 = 8/16" (or 1/2") length The NAS523 Rivet Symbol on Blueprints

The standard, developed by the Aerospace Industries Association (AIA), is not a rivet itself, but rather a "Fastener Code." It provides a compact, four-quadrant symbol used on engineering drawings to identify the specific type, material, head style, and installation method of rivets, replacing long, complex text callouts.
Typically indicates the rivet material or alloy type.
