Arnold & Shinjo’s HR Rivet Nut is a solution for fastening high-strength metals or materials of any type, thickness, and hardness, and it's installed by stamping presses to provide the advantages of in-die fasteners. The nuts can be used in panels from 0.4-4.5 mm (0.02-0.2 in) thick. They fix to a panel by forming the nut instead of the panel. This enables the use of high-density metals that cannot be welded or pierced efficiently. They're useful in producing lightweight vehicles. Life-cycle costs are lower compared to competing technologies such as weld nuts—environmental costs associated with welding gases, power consumption, and heavier vehicles are avoided. Additionally, a single rivet nut can be used in various applications, thus reducing tooling investment.
