Rivet nut stud designed for steering column applicationOEM applications are characteristically different and challenging. Often, design modifications are required to a rivet, rivet nut or a rivet nut stud in order for our products to fulfill the requirements of the application and the Customer. In one particlar instance, a customer approached Gesipa Blind Riveting Systems to design a rivet nut stud to meet very specific and tight application parameters for use in a steering column.
The design team at Gesipa Keighley worked on a standard M6 rivet nut stud design modifying it to give a high clamp with minimal set length in the steering column. This was done by reducing the counter bore just enough to grip the required material without lowering the torque and using different materials to ensure correct setting for the application. Poke-yoke troubleshooting was conducted at Gesipa's facility in Keighley to check the performance of this redesigned rivet nut stud during assembly. During this process, the vision inspection system picks the product up and rotates it in front of the camera checking every rivet nut stud for short assembly, rivet nut length, stud length, crimp root diameter, crimp crest diameter, malformed crimp and rivet nut head diameter.
Gesipa started manufacturing a standard range of rivet nut stud in its UK facility in Keighley, West Yorkshire in 2010 and now produces sizes M4 to M12 in a variety of materials and stud lengths to match customer requirements. Currently being used in applications such as automotive, refrigeration plant, HVAC, securing panels, securing hoses and electrical components, rivet nut studs have huge potential in the aluminium extrusion market and various other applications using thin metals.
