Non-metallic washers melt or deform. Standard NAS523 washers are typically rated for -65°F to +250°F. If your application exceeds 250°F, you must specify a special material variant (e.g., Polyimide) or switch to a metallic standard.

The NAS523 standard, published by the Aerospace Industries Association (AIA), dictates a specific method for coding solid rivets on engineering drawings, blueprints, and structural repair manuals (SRMs). AIA/NAS NAS523 - FASTENER CODE As of today, the official NAS 523 Rev

The purpose of NAS523 is to provide a standardized, space-saving way to specify rivets, lockbolts, and other permanent fasteners on complex aerospace drawings, ensuring clarity and eliminating ambiguity in part identification and installation. It is considered the only standardized method in the United States for this purpose.

Represented by a number indicating 1/32-inch increments (e.g., a "3" means 3/32" diameter). The NE quadrant specifies the and instructs the

The two letters immediately following "NAS523" designate the specific type of rivet, which combines its material composition and head shape.

Aerospace projects involve thousands of parts sourced from various global suppliers. NAS523 provides a universal language that manufacturers, quality inspectors, and maintenance crews all understand. This consistency reduces the risk of human error during both the manufacturing and maintenance phases. Digital Integration and PDF Accessibility
