Abstract

A magnetized nut for fastening a compressor wheel of an exhaust turbocharger to a turbo shaft. The nut has a base body made of a non-magnetic material forming a hollow space for accommodating a magnetic material, and a method for the production of the magnetized nut. In order to provide a magnetized nut that is produced in a simple and cost-effective manner and ensures as equal a distribution of mass as possible with regard to the rotational axis of the nut, the magnetic material is introduced into the hollow space using injection molding.
