Abstract
A profiled nut () of a screw drive includes a sleeve () produced from sheet steel, has a non-cuttingly formed rolling profile () on the inner circumference for rolling contact with rolling bodies and is hardened in a heat treatment method at least in the region of the rolling profile (). An inner lateral surface of the sleeve () having the rolling profile () is hardened and has a higher Rockwell hardness. An outer lateral surface of the sleeve () is designed such that it can be welded and has a lower Rockwell hardness.
