The advantages of the press-in connection technology lie in the particular durability and high torsional strength when transmitting tightening and torque in the connection. The diversity in the technical design of press-in elements as well as the economy and precision of the press-in process enable a very wide range of developments in the design of complex sheet metal constructions.

Press-fit technology is used wherever no thermal or other joining processes are permitted. These branches of industry include mechanical and apparatus engineering, electronics (e.g. switch cabinet construction), the automotive industry or, for example, lightweight construction in aerospace engineering.

Special press-fit fastening elements with heavy-duty threads are required to achieve a high level of torsion resistance when transferring torsional and tightening torques in thin-walled sheet metal.

These can be installed with a positive and non-positive fit by pressing the elements into a flowable base material using cold forming. In this process, the base material is displaced during the pressing-in process - cold flow begins. The excess material flows and
finally wraps around the shank of the press-fit element.

A special shape in the head area and / or a toothing on the press-fit element ultimately prevents twisting within the connection.
