Rivet Code Pdf — Nas523
NAS523 is a controlled document published by the Aerospace Industries Association (AIA), and it is an evolving standard. To ensure you are working with the correct specifications, you should use the most current version. The known published revisions include NAS523-2007 (Revision 29), NAS523-2013 (Revision 30), and NAS523-2014 (Revision 31), which is likely the most up-to-date edition.
If a drawing is too crowded, a larger cross may be placed to the side with a leader line pointing to a smaller cross at the exact installation site.

The NAS523 rivet code PDF is a comprehensive document that outlines the specifications for NAS523 rivets. The PDF document provides detailed information on:
NAS523 rivets are typically (common for general aerospace use), though other materials exist with suffix letters (e.g., NAS523-6-8C for corrosion-resistant steel). The standard finish is plain or chem-film coated depending on procurement spec.

Examples: (Universal Head), MS20426 (100° Countersunk Head), NAS1097 (Reduced Flush Head). 2. Top-Right Quadrant: Material Code
Interpretation: This code corresponds to a protruding head rivet (likely a universal head type). The diameter code of 5 gives a diameter of 5 × 1/32 inch = 0.15625 inch (approximately 5/32 inch). The "F" indicates the manufactured head is to be installed on the far side of the assembly. The blank lower left quadrant confirms that no countersinking or dimpling is required (consistent with a protruding head rivet). The length code of 8 corresponds to the designated grip length.
The is an industry-standard geometric crosshair symbol used on aerospace blueprints to compress a rivet's type, material, diameter, length, and installation method into a single, scannable icon. Developed by the Aerospace Industries Association (AIA) , this "Fastener Code" standard practice ensures that aircraft structural engineers, maintenance technicians, and mechanics have precise manufacturing data directly on production drawings without cluttering schematic layouts. To properly apply these specifications in structural fabrication or sheet metal repair, professionals consult specific reference resources like the NAS523 Rivet Identification Guide PDF on Scribd .
