Abstract
The invention provides a new and improved fastener for attaching a tail lamp assembly to an apertured vehicle body panel. According to the invention, a stud member has a first shank portion which is externally threaded for threaded attachment within a threaded aperture of the tail lamp assembly. A second shank portion of the stud member has internal threads formed therein and a smooth outer cylindrical surface which is adapted for non-interfering insertion through an aperture of the vehicle body panel. A nut member includes a screw encapsulated within a molded nut. The molded nut has a bearing surface adapted to engage against the panel member and the screw has an external screw thread adapted for threaded engagement within the internal threads of the stud member second shank portion so that the tail lamp device is attached to the panel. A cup-shaped retainer is preferably carried by the stud member axially intermediate the first and second shank portions and has an outer peripheral rim adapted to bear against the face of the panel to limit insertion of the stud member into the panel aperture. The cup-shaped retainer also has a recessed cup portion radially intermediate the stud member and the peripheral rim adapted to retain a seal in a sealing interposition between the fastener and the panel.
