The NAS523 code is a standard practice in the aviation industry used to provide a shorthand identification of fasteners—specifically rivets—on engineering drawings. It uses a distinctive "crosshair" symbol divided into four quadrants (NW, NE, SW, SE) to detail the rivet's part number, diameter, length, and installation method. NAS523 Rivet Code Quadrants The code is read as follows:

- Normal to Tightened: If 2 out of 5 consecutive lots are rejected.
- Tightened to Normal: If 5 consecutive lots pass.
- Normal to Reduced: Permitted only with customer approval and 10 consecutive lots passed.
SE (Southeast - Lower Right): Defines the fastener length in 1/16" increments (e.g., -6 = 6/16" or 3/8"). Key Components of the NAS523 Standard The NAS523 code is a standard practice in
This standard defines a specific type of fastener—namely, a reduced diagonal head, internal wrenching screw made from corrosion-resistant steel. In the world of aerospace engineering, NAS523 is a critical component known for its high strength and space-saving design. Normal to Tightened : If 2 out of
