The NAS523 specification is the aerospace standard for . Specifically, it dictates the head markings and codes used to identify blind rivets and solid rivets in aircraft construction. Because structural integrity is paramount in aviation, knowing how to interpret these markings is a critical skill.
The (National Aerospace Standard) is the industry-standard code used on aircraft technical drawings to specify exactly which fastener should be installed at a given location. It uses a "crosshair" symbol divided into four quadrants—Northwest (NW), Northeast (NE), Southwest (SW), and Southeast (SE)—to communicate complex fastener specifications in a compact format.

In aerospace manufacturing, precision is not just a standard—it is a safety requirement. Among the thousands of hardware standards used in the aviation industry, National Aerospace Standards (NAS) govern some of the most critical components holding an aircraft together. If you are searching for , you are likely looking for the definitive reference sheet, code breakdown, or standard document for NAS523 rivet identification.
