Abstract
The present application provides a fastener for fastening a first component in a second component having a circular hole. The fastener includes a main body and a retaining member. The main body includes a head for connecting the first component and a shaft portion extending from the head. The retaining member includes a receiving barrel and a plurality of retaining arms. The shaft portion passes through and is connected to the receiving barrel to limit the axial and radial movements of the retaining member along the shaft portion relative to the main body. The plurality of retaining arms extend upwardly from the receiving barrel and are distributed about the central axis of the receiving barrel. The plurality of retaining arms are deflectable towards the shaft portion. The plurality of retaining arms are located between the shaft portion and a hole and abut against the hole to retain the second component between the head and the plurality of retaining arms when the retaining member is inserted into the hole. The main body is made of a first material, and the retaining member is made of a second material that is more wear-resistant than the first material.
