Abstract:
1. A hollow fastener element for an electrically conductive attachment of an electrical terminal to a sheet metal part, wherein the hollow fastener element has a head part, a tubular rivet section projecting from said head part and merging via a conical contact surface for the sheet metal part into the head part, a tubular guide section is arranged concentric to the tubular rivet section and radially inside the latter, with a ring gap being provided between the tubular guide section and the tubular rivet section and with the tubular guide section projecting beyond a free end of the tubular rivet section, wherein on attachment of the fastener element to the sheet metal part the tubular rivet section is bent outwardly when the free end of the tubular rivet section is pressed on by a die button, wherein features providing security against rotation are provided at the conical contact surface, wherein the hollow fastener element has a bore having a first portion with a first diameter within said head part and a second portion having a second diameter within said tubular guide part, with said second diameter being larger than said first diameter, said first portion being sized for the formation of a thread by one of a thread cutting screw and a thread forming screw and wherein a mount for the rotationally secure attachment of the electrical connection device to the fastener element is provided at the end face of head part remote from the rivet section.
