Jürgen Hierold: That's right. Additional fastening elements are not necessary. With this flowform fastening procedure, the nut thread is formed directly inside the through-funnel. And that can only be an advantage. And the fact that all the parameters necessary for process-reliable screw fastening are also available for flowform fastening is crucial. And there is absolutely no need to pre-drill or punch the component. This provides a tremendous rationalisation effect in the manufacture of metal components. The entire screw fastening process has been optimised in such a way that extremely short cycle times can be achieved in assembly. For modern car body construction this translates into a cycle time per screw fastening of less than two seconds!
