The standard is crucial for maintaining structural integrity during repairs. It guides Aircraft Maintenance Engineers (AMEs) in selecting the correct alloy, such as the single-dimpled "AD" rivet for general use or "icebox" rivets that require heat treatment and refrigeration before installation. By standardizing these codes, NAS 523 eliminates ambiguity in high-stakes environments, preventing issues like galvanic corrosion by ensuring fastener materials match the surrounding structure.

The aerospace industry suffers from billions of dollars in losses due to counterfeit fasteners. A verified provides the dimensional tolerances (e.g., washer inner diameter, thickness, material hardness) required to test incoming parts. If a part does not match the PDF, it is rejected.

The length of the rivet should be chosen so that the shop head (the formed head) is properly sized. A rule of thumb is that the rivet should protrude 1.5 times its diameter through the structure.
