Indicates the fastener's basic part number (e.g., AN or MS) and its material composition. For example, the code "BJ" identifies an MS20470AD universal-head rivet made of 2117-T3 aluminum alloy.

If you are looking at the head of a rivet, the NAS523 standard helps you immediately identify its . Symbol / Marking Alloy Material (Temper) Typical Application Plain (No Marking) 1100-F (Commercially pure aluminum) Non-structural parts, light sheet metal work. Raised Teat / Dot 2117-T4 (AD - Aluminum Alloy) Universal use; most commonly used in aircraft riveting. Raised Cross / Plus Sign 5056-H32 (B - Aluminum Alloy) Joining magnesium alloys. Raised Double Bar 2017-T4 (D - Aluminum Alloy) Requires heat treatment before driving (Icebox rivet). Raised Raised Triangle 2024-T4 (DD - Aluminum Alloy)

The code covers various rivets, including standard AN426 (100° head) and 1097 smaller head rivets. Where to Find and Download NAS523 nas523 pdf top

The upper-left quadrant identifies the basic part number series (such as or MS military standard specifications) and the precise chemical alloy from which the fastener is made.

stands for National Aerospace Standard 523. It is a comprehensive standard that defines a 4-cornered, crosshair-shaped symbol used on blueprints to designate specific rivets. Instead of listing multiple fastener details (material, diameter, length) in text format, the NAS523 code offers a consolidated visual representation, reducing clutter on complex aerospace drawings. Key Aspects of the NAS523 PDF Standard

An NAS523 code looks like a confusing string of letters and numbers, typically organized into a quadrant or a linear sequence. To understand the top PDF reference charts, you must know how to dissect this code. If you are looking at the head of

: Aerospace standards change. Ensure the PDF chart you are using matches the revision letter called out in your specific aircraft's structural repair manual (SRM) or engineering orders.

If you are working in a commercial MRO (Maintenance, Repair, and Overhaul) environment or defense facility, you must rely on fully updated, legally compliant standards. The complete official document can be purchased through the GlobalSpec NAS523 Fastener Code Standard Page or the Accuris Standards Store AIA NAS523 Page. These industry-tier publications detail all permanent deformation fastener rules, historical revisions, and full cross-referencing capabilities. Quick Reference: Standard Aviation Rivet Conversions
