In sheetmetal works and professional press shops good use is made of the classical advantages of piercing nuts and press-in screws. The processing of the fastening elements is integrated into the manufacturing process of the sheetmetal parts and the finished component is obtained without an additional work station being necessary. This saving of further work steps can reduce the production costs by up to 30 %. The tool-bound processing ensures that the position tolerances of the connecting elements are reliably maintained.
