The invention relates to a method for mounting a fastener element (1), such as a screw or a nut, in a component (2). The fastener element (1) is provided with a deformable, cylindrical portion (3) which has an axis of symmetry. The cylindrical portion (3) is inserted in a through-hole (4) in the component (2), whereafter the cylindrical portion (3) is deformed in its longitudinal direction by means of a compressive force, so that the length of the cylindrical portion (3) is reduced. By causing the fastener element to rotate at a predetermined rotational speed so that frictional heat is generated between the contact surfaces of the fastener element (1) and the component (2), there is created a combined rivet and frictional welding joint between the fastener element (1) and the component (2). The invention also relates to a tool for mounting the fastener element in accordance with the method. |
