Abstract
A method for inserting a component through a surface of a workpiece made of a first material uses friction-induced plasticity of the latter to attach the component to the workpiece. The component includes a head portion having a base and a working end being threaded, and an insert portion having a penetrating end and provided with a threaded bore closed at its penetrating end, to initially receive the threaded working end. The outer surface of the insert portion being made of a second material harder than the first material, a rotary tool can be used to insert the component through the workpiece surface, by rotating the rotary tool in a first direction while applying an axial force onto the head portion base to produce substantially full insertion of the insert portion, and by maintaining the axial force during a sufficient setting time without rotation to produce the attachment.
