Abstract
A fastening member assembly includes an axially extending shank (1) with a leading end to be inserted into a receiving material and a trailing end with a load engagement member (2). The leading end has a tip (3). An axially extending section of the shank (1) is laterally enclosed by a sleeve (4) adjacent its leading end, and a stop (5) formed adjacent the trailing end of the sleeve. A bush (6) formed of impact-resistant plastics material encloses an axially extending section of the shank and extends from the stop (5) towards the leading end. When the fastening member is driven, the sleeve penetrates into a hard receiving material and the bush (6) deforms for absorbing excess driving energy, so that a member in the form of a retaining part being connected to the receiving member, is not destroyed.
