Various repositories hold Rivet Identification Guides (NAS523) that include visual charts. Rivet diameter in 1/32" increments and manufacturer head

For flush riveting, the PDF includes the exact radius and depth of the 100° countersink. A mismatch between the rivet head and the countersink angle creates a stress riser. The NAS523 PDF includes go/no-go gauge dimensions.

The NAS523 standard references and is referenced by numerous other aerospace standards, including:

: Identifies an MS20470AD (or AN470AD ) universal-head rivet made of 2117-T3 aluminum alloy. 100-degree countersunk flush head rivets (used on exterior

On aerospace blueprints and structural repair drawings, the NAS523 code is rarely written as a single line of text. Instead, it is displayed using a .
