M7B8.2 Solid Rivet

This video offer a comprehensive guide to solid shank rivets, which are essential, cost-effective fasteners used extensively in aircraft construction and repair. These texts detail the standard identification systems—such as MS, NAS, and AN—which use specific codes to denote a rivet's head shape, material alloy, and physical dimensions. Readers can learn about the different applications for universal heads and 100° countersunk heads, the latter of which are critical for maintaining aerodynamic smoothness on high-speed aircraft surfaces. Furthermore, the documents explain the selection of aluminum alloys, distinguishing between the commonly used AD rivets and "ice box" DD rivets that require specialised thermal treatment. Technical instructions are also provided regarding installation mechanics, such as the proper formation of a shop head and the mathematical rules for determining the correct rivet diameter based on material thickness. Ultimately, these references serve as a vital manual for technicians to ensure structural integrity and chemical compatibility when joining aeronautical components.
