Abstract
In a method for making an assembly unit from an assembly bolt (3) that has a bolt head (9) and a shaft (6) and from a sleeve that has an axially movable annular collar (11) toward the head that surrounds a partial axial region of the shaft, first the shaft that has a counterpart back-engagement part is introduced into the sleeve, and then at least one back-engagement part on the sleeve is created by means of a stamping oriented essentially inward from the outer jacket face. The stamping has an action that is oriented radially inward and an action oriented toward the bolt head (9). In the stamping, a counterholder presses against the bearing face (22) of the annular collar (11) oriented toward the bolt head (9).
