The invention relates to a device for setting fastener elements or pins, particularly to a screw-setting device. The device comprises a housing in which a retainer shaft for a setting tool is mounted at least for axial displacement, at least one advance drive mechanism within the housing and adapted to be connected to the retainer shaft, a switching sleeve mounted for displacement together with the retainer shaft and defining at least one switch-off point, at least one sensor device supported in the housing for defining the switch-off point, and an adjustment mechanism for adjusting the switch-off point. In known devices of this type, the accurate and rapid adjustment of the switch-off point is difficult. According to the invention the adjustment mechanism is provided within the housing between the switching sleeve and the retainer shaft. The retainer shaft additionally or alternatively cooperates with a stop to limit its stroke within the range of the stroke of the advance drive mechanism with the aid of the switching sleeve to thereby prevent the retainer shaft from being advanced excessively beyond the switch-off point in the absence of a fastener element.
