A fastener having a shaft, a threaded portion, a positioning member and a rivet head. The shaft has a first diameter and extends from a first end to a second end. The threaded portion is positioned on the shaft. The positioning member is provided on the shaft proximate the second end. The rivet head extends from the second end of the shaft in a direction away from the first end, with the rivet head having a second diameter which is less than the first diameter of the shaft. 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, thereby securing the fastener to a mating member which is positioned between the positioning member and the deformed rivet head.

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. 2. The fastener as recited in claim 1, wherein the threaded portion has spiral threads which extend from proximate the first end of the shaft toward the second end. 3. The fastener as recited in claim 2, wherein the shape and pitch of the spiral threads results in large frictional forces are present when a nut is moved into engagement with the spiral threads, thereby causing the threaded portion to be self locking. 4. The fastener as recited in claim 2, wherein the positioning member is provided between the spiral threads and the rivet head. 5. The fastener as recited in claim 1, wherein the positioning member extends radially outward around a circumference of the shaft. 6. The fastener as recited in claim 4, wherein the positioning member has a shoulder which is positioned proximate the rivet head. 7. The fastener as recited in claim 1, wherein the rivet head has a tubular rivet configuration. 8. The fastener as recited in claim 7, wherein the rivet head has an opening which extends from a free end of the rivet head inward toward the second end of the shaft, the opening the cavity has a circumferentially extending sidewall, the opening facilitates the deformation of the rivet head, the cavity reducing the amount of force needed for application by rolling or deforming the sidewall outward. 9. The fastener as recited in claim 1, wherein the rivet head has a square rivet configuration. 10. The fastener as recited in claim 9, wherein the cavity extends between two opposed sidewalls of the rivet head, the cavity reducing the amount of force needed for application by rolling or deforming the sidewalls outward. 11. 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, the positioning member extending radially outward around a circumference of the shaft;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 an opening which extends from a free end of the rivet head inward toward the second end of the shaft, the opening has at least one sidewall, the opening facilitating the deformation of the at least one sidewall 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 which is positioned between the positioning member and the deformed rivet head 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. 12. The fastener as recited in claim 11, wherein the threaded portion has spiral threads which extend from proximate the first end of the shaft toward the second end, the shape and pitch of the spiral threads results in large frictional forces are present when a nut is moved into engagement with the spiral threads, thereby causing the threaded portion to be self locking. 13. The fastener as recited in claim 12, wherein the positioning member is provided between the spiral threads and the rivet head. 14. The fastener as recited in claim 11, wherein the rivet head has a tubular rivet configuration. 15. The fastener as recited in claim 11, wherein the rivet head has a square rivet configuration. 16. 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, the threaded portion having spiral threads which extend from proximate the first end of the shaft toward the second end, the shape and pitch of the spiral threads resulting in large frictional forces are present when a nut is moved into engagement with the spiral threads;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;a positioning member provided on the shaft proximate the second end, the positioning member provided between the spiral threads and 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 which is positioned between the positioning member and the deformed rivet head 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. 17. The fastener as recited in claim 16, wherein the rivet head has a tubular rivet configuration. 18. The fastener as recited in claim 17, wherein the rivet head has an opening which extends from a free end of the rivet head inward toward the second end of the shaft, the opening has a circumferentially extending sidewall, the opening facilitates the deformation of the rivet head, reducing the amount of force needed for application by rolling or deforming the sidewall outward. 19. The fastener as recited in claim 16, wherein the rivet head has a square rivet configuration. 20. The fastener as recited in claim 19, the rivet head has a cavity which extends from a free end of the rivet head inward toward the second end of the shaft, the cavity extends between the two opposed sidewalls of the rivet head, the cavity facilitates the deformation of the rivet head, reducing the amount of force needed for application by rolling or deforming the sidewalls outward.
