Abstract: A tool for inserting or removing a tang-free wire thread insert is described, the entraining blade of which is manually fastenable and replaceable within the axial recess of the spindle body by means of a latching connection. In addition to the secure removal of wire thread inserts, this tool construction also ensures a quick replacement of worn entraining blades of the tool. Furthermore, a production method for such a tool is described.

Abstract: A threaded element in the shape of a wire thread insert with a specific geometric design is disclosed. This threaded element contains, in particular, a narrowed helical winding of at least two helical winding sections that enclose one or a plurality of sequential secants. Based on this geometric design of the threaded element, a matched installation process is described.

Abstract: A wire thread insert comprises besides a cylindrical helix consisting of a plurality of coils a moving tang projecting into the interior of the helix for installing the wire thread insert into a receiving thread. The wire thread insert is connected to the cylindrical helix via a bending portion such that the moving tang can be redressed into the receiving thread after installation of the wire thread insert. The wire thread insert is installed by means of an installation tool with a mounting spindle, which installs the wire thread insert in the receiving thread via a moving shoulder and the moving tang. A compression blade provided at the mounting spindle bends the moving tang back into the receiving thread while the mounting spindle is removed from the installed wire thread insert.

Abstract: The present invention discloses a self-piercing element, that can be fastened to a structural component by means of piercing and beading. Additionally, the present invention discloses an apparatus for seating the self-piercing element and a corresponding method. The self-piercing element comprises a functional head, a seat geometry and a cutting geometry, while the cutting geometry has a radially outwards arranged, centering exterior bevel, a radially inward arranged interior bevel and a cutting edge arranged in between.
