Nas523 Rivet Code Pdf

The first number following the material code specifies the shank diameter. In aerospace standards, rivet diameter is measured in . -3 : 3/32 inch diameter -4 : 4/32 inch (1/8 inch) diameter -5 : 5/32 inch diameter -6 : 6/32 inch (3/16 inch) diameter 4. Rivet Length (The Second Number)

: This specifies the rivet's diameter in increments of 1/32 of an inch. It also uses letters like (Near side) or nas523 rivet code pdf

Many university aerospace departments and FAA Part 147 maintenance schools host free, downloadable PDF reference sheets containing the full NAS523 quadrant graphics. Search for university file repositories using search strings like filetype:pdf NAS523 rivet chart . The first number following the material code specifies

This adherence to a unified standard avoids confusion. Codes like "RIVET CODE PER NAS523" seen in parts lists are a direct instruction to use this specific coding system for fastener identification. The standard covers all fasteners whose installation causes permanent deformation, often requiring destruction for removal. This is particularly vital for blind rivets, which are ideal for single-sided access applications. For instance, in some designs, rivets with grips longer than their diameter are not required to meet standard expansion requirements, highlighting that NAS523 is part of a complex set of interrelated engineering design rules. Rivet Length (The Second Number) : This specifies

The bottom-right quadrant specifies the shank diameter of the rivet. In aerospace standards, rivet diameter is almost universally measured in . 3 = 3/32" 4 = 4/32" (1/8") 5 = 5/32" 6 = 6/32" (3/16") 4. The Bottom-Left Quadrant: Rivet Length

: Titanium (High strength-to-weight ratio for advanced structures) 3. Rivet Diameter (The First Number)

Critical Note: In the official NAS523 PDF tables, the length is measured from under the head for universal head rivets, or overall length for countersunk rivets. Always verify the grip length (material stack thickness) plus clinch allowance using the formula provided in the specification.
