This quadrant dictates the total length of the rivet. Rivet length is measured in .

Direct conversions between military standards (MS), National Aerospace Standards (NAS), and Army-Navy (AN) part numbers. Best Practices for Shop Use

The right section indicates how the skin material should be prepared to receive the rivet head. This is crucial for aerodynamic flush riveting.

If you need help locating specific structural data, let me know: nas523 rivet code pdf

The NAS523 rivet code PDF explicitly states a shear strength of when heat-treated to the T6 condition. An aluminum NAS523 (if incorrectly substituted) would fail at 38,000 psi.

The NAS523 standard helps you break down the confusing string of letters and numbers found on a blueprint. Here is the logic you would find in the document:

: Aluminum Alloy (2024-T4, high strength, also an Icebox rivet) This quadrant dictates the total length of the rivet

The NAS (National Aerospace Standard) prefix indicates a fastener designed for high-performance aircraft environments. Specifically, refers to a solid, protruding head rivet made of corrosion-resistant steel (typically A286 or similar superalloy). These rivets are used in airframe structures that require high shear strength and resistance to elevated temperatures (up to 800°F/427°C).

This article serves as a deep dive into the NAS523 standard, explaining its structure, application, and why locating a is essential for aviation maintenance technicians (AMTs) and structural engineers. What is the NAS523 Rivet Code? Best Practices for Shop Use The right section

If this exact same fastener were represented inside a blueprint cross symbol, you would see on top, 4 on the left, and 6 on the right. Why You Need a Digital NAS523 PDF Reference Chart

Interpretation: This is a specific rivet series (AD) with a diameter code of 4. Since it is a rivet callout, the diameter is calculated as 4 × 1/32 inch = 1/8 inch (0.125 inch). The manufactured head is to be installed on the near side (N) of the assembly. The lower left quadrant contains a "C", indicating the hole must be countersunk to accept a flush rivet head. The length code is 6.
