To provide a rivet for fastening a component to a vehicle body frame, with a stem and a body forming a single component assembly.
In the rivet, a head portion 6 of the stem 2 and a head portion 3 of the body 1 have an inclined face 8 and a ramp 9, respectively, and the inclined face 8 and the ramp 9 in the position of maximum penetration of the stem 2 are coincident and determine an external continuity of a head portion of the rivet, whilst a rotation of 90° of the stem 2 signifies the sliding motion of the inclined face and the separation of the head portion 6 of the stem 2 from the head portion 3 of the body 1, allowing the drawing of the stem 2 through its head portion 6 and the removal of the body 1 by pulling. The stem 2 has a protrusion 10 which prevents the independence of the stem 2 from the body 1 and allows the extraction and removal of the whole assembly of the rivet through pulling the stem 2.
