Patent ID: 7988394

Claim:
A hollow fastener element for an electrically conductive attachment of an electrical terminal device ( 104 ) to a sheet metal part, wherein the hollow fastener element ( 10 ) has a head part ( 14 ) and a tubular rivet section ( 16 ), wherein a tubular guide section ( 18 ) is arranged concentric to the tubular rivet section ( 16 ) and radially inside the latter, with a ring gap ( 20 ) being provided between the tubular guide section ( 18 ) and the tubular rivet section ( 16 ), and with the tubular guide section projecting beyond a free end of the tubular rivet section, and wherein on attachment of the fastener element to the sheet metal part the tubular rivet section is bent outwardly when a free end of the tubular rivet section ( 16 ) is pressed on by a die button ( 56 ) with the tubular rivet section ( 16 ) merging via a contact surface ( 12 ) for the sheet metal part into the head part ( 14 ) and with features ( 30 ) providing security against rotation being provided at the contact surface and/or at the rivet section ( 16 ), wherein said head part has an end face remote from said tubular rivet section ( 16 ), wherein the hollow fastener element has a bore ( 38 ), at a point at which a thread is formed by screwing-in a thread cutting or thread forming screw ( 106 ) thereby forming an electrically conductive connection between said screw and said element and wherein a mount ( 80 ) for a rotationally secure attachment of the electrical terminal device ( 104 ) to the hollow fastener element is provided at the end face of said head part ( 14 ).
