NAS523 is the AIA‘s national aerospace standard for fastener codes. BACD2074 is Boeing’s internal design standard that references NAS523 for fastener callouts on Boeing engineering drawings.
NAS523 PDF Top: The Ultimate Guide to Aerospace Rivet Codes and Specifications
At least four major revisions: Rev 28 (1993), Rev 29 (2007), Rev 30 (2013), and Rev 31 (2014-current).
is an aerospace standard practice used for identifying fasteners that undergo permanent deformation during installation, such as solid rivets. This standard defines a unique four-quadrant "crosshair" symbol
Overall, I would rate the NAS 523 PDF as follows:
The baseline rule of thumb requires choosing a shank diameter that is at least three times the thickness of the thickest sheet being joined (
Contains a two- or three-letter code that identifies the fastener part number (such as AN or MS standards) and the material/alloy . For example, the code "BJ" identifies a standard MS20470AD universal-head rivet made of 2117 aluminum alloy.
Indicates rivet diameter (in 1/32" increments) and manufacturer head location.
