Abstract: The installation tool for a wire thread insert includes: a drive unit which provides a switchable rotation movement between a first and a second direction, a mandrel body with a drive section for rotating the mandrel body and with a drive section for rotating the mandrel body and with a thread section onto which the wire thread insert can be screwed or rotated on, an installation blade as well as a torque clutch consisting of a form-fit and force-fit clutch upper and lower parts engaging each other, of which the upper part is connected with the drive unit in a torque-proof manner and the lower part is connected with the mandrel body in a torque-proof manner. With a decoupled relative rotation between the clutch parts, caused by exceeding a limit torque between the clutch parts, relative movement between the mandrel body and the installation blade can be generated.

Abstract: A mounting spindle with a thread that is formed adapted to the thread-protecting element, formed as a helical wire, serves as a mounting tool with the mounting method. The helical wire is fixed on the mounting spindle by frictional engagement, which is greater than the torque necessary for mounting the helical wire into the receiving threads. The mounting spindle with the helical wire fixed thereon is then threaded into the receiving threads. Then, the mounting spindle is removed from the helical wire by rotation opposite to the mounting direction. The frictional force is achieved by a reduced-diameter end section of the helical wire.

Abstract: A method for mounting a screw and a thread-armoring element in a receiving thread of a component is described, in which the thread-armoring element is immobilized on the screw and the screw with the thread-armoring element immobilized on it is then screwed into the receiving thread of the component in one single work step. An arrangement comprising a screw and a thread-armoring element immobilized on it for carrying out said method is also described.

Abstract: A screw connection comprising a wire thread insert 8 which is inserted between a female thread M of a workpiece 4 and a male thread B of a screw 6 and which consists of a helically coiled wire thread member having a male thread adjacent internal thread 10 and a female thread adjacent external thread 12, characterized in that the profile angles ?B, ?M of the internal and external threads 10, 12 of the wire thread insert 8 are smaller than the respective profile angles ?B, ?M of the male thread B and, respectively, the female thread M such that when the screw connection is loaded by a predetermined biasing force KV the load flanks of the internal and external threads 10, 12 of the wire thread insert 8 engage the associated load flanks of the male and female threads B, M in full contact relationship.

Abstract: A device for joining a first component A and a second component B while leaving a joining gap SP includes a bolt 4 and a compensating coil 2 for compensating tolerances of the joining gap. The compensating coil is adapted to be fixed to the bolt 4 by frictional engagement means and/or releasable positive engagement means. The dimensions of the compensating coil are adapted to a helical rim hole portion 6 of the first component A such that actuation of the bolt 4 causes the compensating coil to rotate through the helical rim hole portion until it fills the joining gap for the purpose of tolerance compensation, and the frictional engagement means and/or releasable positive engagement means is overcome by further actuation of the bolt 4 so that the bolt can be screwed into a threaded hole of the second component B to join the two components.

Abstract: An assembly for automatically compensating variations of the spacing between first and second structural members due to manufacturing and/or mounting tolerances. The assembly comprises a mounting bolt, a base element, and an adjustment sleeve. The adjustment sleeve has a drive portion adapted to be engaged with the nut by frictional drag and rotatable relative to said mounting bolt when said frictional drag has been overcome. The drive portion comprises an internal annular plastic portion which projects from the wall of the adjustment sleeve radially outwards sufficiently so as to frictionally engage the threads of the mounting bolt to provide for said frictional drag.
