The is a standardized symbol used in aviation diagrams and engineering drawings to specify precise details for fastener installation. Instead of long text strings, it uses a single four-quadrant "crosshair" symbol to communicate the rivet part number, material, size, and necessary hole preparation. Quadrant Breakdown

Imagine you see an NAS523 cross on an engineering drawing with the following values: MS20470 Top-Right: AD Bottom-Right: 4 Bottom-Left: 6

As of 2025, many original equipment manufacturers (OEMs) like Boeing (BMS specifications) and Airbus (ABN specifications) have moved toward in-house standards. However, for:

When the quadrant symbol cannot be drawn, the NAS523 code is written as a continuous text string. A typical text string looks like this: NAS523BB4-6NAS523BB4-6 Let's deconstruct this example piece by piece: The Prefix: Standard Identification : Letters like D (Dimpled), C (Countersunk), or

The "rivet code" symbol used in NAS523 is a crosshair, dividing a circle into four quadrants, each containing a specific piece of data about the fastener.

A specialized fastener often designated as "APZ".

While general reference charts provide basic overviews, structural engineers, FAA-certified Airframe and Powerplant (A&P) technicians, and aerospace quality control inspectors must rely on official, controlled PDF documents. Here is why: 1. Exact Material Substitution Tables Note: The table above acts as a brief

Pure aluminum (1100), often used for non-structural applications.

The NAS523 code is visually represented as a four-cornered symbol (often resembling a crosshair or divided box) placed on blueprints. Each corner represents a different aspect of the fastener:
