Abstract
A component for use with a rotary tool and to be inserted through a surface of a workpiece made of a material showing friction-induced plasticity such as aluminum, is rotated in a first direction while an axial force of a sufficient magnitude is applied onto the component to produce insertion thereof by plasticizing the material through friction. The component includes a connection portion and an insert portion having a penetrating end defining a maximum outer diameter, and an outer surface forming at least one generally circular anchoring recess defining a minimum diameter. The connecting portion is adapted not to substantially deform upon insertion of the insert portion, and a ratio of minimum diameter and maximum diameter is between about 65% and 90%.
