Abstract
A component for use with a rotary tool is designed to be inserted through a surface of a workpiece made of a first material showing friction-induced plasticity for attachment to the workpiece. The component has a head portion having a base and a working end being threaded at its outer surface, and further has an insert portion having a penetrating end and extending along an insertion axis. At least an outer surface of the insert portion is made of a second material harder than the first material. The insert portion is provided with a threaded bore closed at its penetrating end and extending along the insertion axis to initially receive the threaded working end. The head portion base is adapted to be secured to the rotary tool for rotation in a first direction while applying an axial force of a sufficient magnitude onto the head portion base to produce substantially full insertion of the insert portion along the insertion axis by plasticizing the first material through friction and to produce attachment after a sufficient setting time.
