ABSTRACT:
A fastening element is set in a receiving material, such as concrete, stone and the like, by driving it through the base of a blind borehole previously formed in the receiving material. When the fastening element is driven initially, it moves through a sleeve and expands and secures the sleeve in the blind borehole. Accordingly, the fastening element is fixed in the receiving material and is also secured by the sleeve in the range of the borehole in the receiving material. A fastening element assembly made up of a fastening element and a sleeve can be used.
