Abstract

Methods for producing a spindle nut, and spindle nuts produced by such methods are disclosed. The method for producing a spindle nut may include producing a blank which has a sleeve portion and a cylindrical outer surface by non-cutting shaping from sheet metal; and forming a thread provided for cooperation with a threaded spindle in the blank by non-cutting shaping, while maintaining the cylindrical outer surface of the sleeve portion.
