Abstract
A device for setting a self-drilling clamping fastener has a fixed external housing, a sleeve-shaped mounting member in which clamping jaws for gripping the shaft of the fastener are retained, a drive sleeve coupled to a rotary drive and a guide sleeve. The guide sleeve and the drive sleeve both are rotatably positioned in the housing. The guide sleeve can be prevented from turning by detent elements movably positioned in the housing. The drive sleeve and the guide sleeve are coupled to each other so that a force during the drilling process is transferred from the drive sleeve to the guide sleeve. The guide sleeve can be rotated together with the mounting member inside the housing in one direction only in a free-wheel fashion.
