Spin-pull riveting

Blind rivet nuts or blind rivet studs are placed into a pre-drilled component and are then tightened via axial pulling force.

In spin-pull riveting as a joining process of fasteners, the blind rivet is leveled via an internal or external thread and is placed into the pre-drill prior to the setting process. Subsequently, pulling force is applied to the blind rivet via the traction thread. Thus, the blind rivet is deformed on the rear side of the component, which leads to a form-fitting joint between the blind rivet and the component.

After the deformation process is completed, the traction thread is leveled again. For the setting process, the joining position only needs to be accessible from one side. The component must have a fitting pre-drill for the fastener.
