1. A fastener for fastening to a mating member, the fastener comprising:
a shaft having a first diameter, the shaft extending from a first end to a second end; a threaded portion positioned on the shaft; a positioning member provided on the shaft proximate the second end; a rivet head extending from the second end of the shaft in a direction away from the first end, the rivet head having a second diameter which is less than the first diameter of the shaft, the rivet head having a cavity which extends from a free end of the rivet head inward toward the second end of the shaft, the cavity facilitates the deformation of the rivet head; wherein, the rivet head is configured to be deformed such that the deformed rivet head has a third diameter which is greater than the first diameter, the deformed rivet head causing the mating member to engage the positioning member, thereby providing sufficient frictional engagement and force between the positioning member, mating member and deformed rivet head to prevent the movement of the fastener relative to the mating member and secure the fastener in mechanical and electrical engagement to the mating member. |
