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.

Installation tool for a wire thread insert

A metal casting method and a plastic injection molding method in which an insert is molded in molten material such that no molten material enters the interior of the insert. The usage of a wire thread insert as insert has the advantage that for example in an aluminum cast part thread holes can be produced already as part of the casting process. For this purpose, the casting mold, the insert, as well as the casting method are described.
