Abstract

The disclosure relates to a threaded nut of a ball screw drive. The threaded nut includes an inner sleeve made of sheet metal and an outer sleeve made of sheet metal. The inner and outer sleeves are nested axially in one another to form a nut sleeve. A thread of the nut sleeve is helically wound about a longitudinal axis of the threaded nut and forms a ball groove on the inner circumference of the inner sleeve. The outer sleeve is provided along the thread with at least one outer hole into which material of the inner sleeve is molded.
