Abstract

See full text

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.
