Abstract: An explosive powder charge operated fastening element assembly setting device is used to drive a fastening element into a hard receiving material such as concrete, steel and the like. The device includes a striker piston transmitting driving force to the fastening element assembly. The forward end of the striker piston has a marking projection. If excessive driving energy is transmitted from the striker piston to the fastening element assembly, the marking projection forms an imprint in a guidance disk of the assembly. The extent of the imprint provides a gauge of the excessive driving force which results in unsatisfactory insertion of the fastening element. If an annularly-shaped marking projection is used, the imprint formed by it can be viewed from all sides of the fastening element.
