Wire thread insert

A tool for a wire thread for installing the latter on or removing it from a threaded bolt, wherein the wire thread insert is a conically formed wire thread insert comprising a body having a plurality of helically wound windings, in which the plurality of helically wound windings comprises a first end winding and a second end winding delimiting the body at opposite axial ends, and the first end winding has a first integral form-fitting means at a first end section and the second end winding has a second integral form-fitting means at a second end section, so that, in an installed state of the wire thread insert, a form-fit rotation-inhibiting connection with an adjacent component structure can be produced via the first and the second integral form-fitting means respectively, wherein the first and the second integral form-fitting means of the wire thread insert of a bolt thread are oriented radially inwards with respect to the windings of the wire thread insert, wherein the first integral form-fitting means comprises a latching hook adjacent to a recess in the first end section and the second integral form-fitting means comprises an end tang in the second end section, and the tool comprises the following features:

• a. a female installation thread with a thread turn,
• b. a movable stop means with which the thread is selectively blockable and releasable;
• and
• c. an unlocking means which is movable in a radial direction into the installation thread to release a form-fitting means.
