ABSTRACT:
A fastening member to be driven into a hard receiving material, such as concrete, masonry, rock and the like, has an axially extending shank with a drilling head at its leading end and a thread adjacent its trailing end for connecting a load to the fastening member. A device is located on the shank for engagement with a tool for driving the fastening member into the receiving material. Initially, the fastening member drills a blind bore into the receiving material and then an explosive powder charge drives the member into its final position.
