Rivorm® HR rivet nut 
Strong connection, regardless of sheet metal strength

Wide range of sheet thicknesses The Rivorm® product family covers a wide range of applications and is designed for sheet thicknesses from 0.5 mm to 4.5 mm. Depending on customer requirements, the rivet elements are available in strength classes 8 and 10. The riveting process used means that sheet metal strength is irrelevant, making the elements particularly flexible in different material combinations. This allows the fasteners to be used safely and reproducibly in a wide range of applications. In order to be able to respond specifically to different requirements, ARNOLD offers Rivorm® press-in elements in three design versions. This ensures optimum adaptation to the installation space, load, and process environment.
