摘要：A method of forming an electrical connection to a conductive metal panel,wherein the connection includes a conductive metal stud having an annular rivetingportion, an integral intermediate radial flange portion, and an externally threaded studportion, a nut member adapted to be threadably received on the stud member shankportion having an end portion adapted to sealingly contact an annular electrical contactsurface surrounding the shank portion of the stud member. The method includesthreadably assembling the nut member on the stud member shank portion forming anassembly with sealing contact between the member end portion and the stud membercontact surface. The assembly is then oriented with the free end of the stud memberriveting portion opposite the panel, driving the riveting portion through an openingformed in the panel and deforming the annular riveting portion radially outwardly torivet the assembly to the panel and form an electrical contact between the stud memberand the panel. The panel may then be coated with a nonconductive coating which doesnot contaminate the electrical contact surface of the stud member. The method thenincludes threadably removing the nut member, assembling the grounding lug on thestud member in electrical contact with the contact surface of the stud member andthreadably receiving a nut on the shank portion to secure the grounding stud in electrical

contact with the panel. In one embodiment, the stud member, includes a plastic cap and aradial flange which extends radially beyond the cap. The method then includes driving theplunger against the flange portion to drive the riveting portion of the stud memberthrough the panel opening and deforming the riveting portion radially outwardly in a diemember. In another preferred embodiment, the nut member is metal and the methodincludes driving a punch against the nut member, driving the riveting portion of the studmember through the panel opening. In a most preferred embodiment, the rivetingportion pierces an opening in the panel which receives the riveting portion therethrough.
