Patent ID: 6957939

Claim:
A decorative cap and a wheel fastener for a vehicle wheel, comprising: a) a fastener insert body having threads formed thereon encircling the axis of said body; b) said body including one section having an external surface with a polygonal cross-section encircling said axis; c) said body including another section having an external surface with a circular cylindrical cross-section encircling said axis; and d) a cap including one wall segment having an internal surface with a polygonal cross-section; e) said cap including another wall segment having an internal surface with a circular cylindrical cross-section; f) said cap being formed of sheet metal which is deformable both plastically and elastically; g) said circular cylindrical cross-section internal surface of said cap having a predetermined inside diameter; h) said circular cylindrical cross-section external surface of said insert body having a predetermined outside diameter; i) said predetermined inside diameter being sufficiently less than said predetermined outside diameter whereby said other wall segment of said cap is adapted to fit onto said insert such that said other wall segment is plastically and elastically deformed with said elastic deformation forming at least a 0.002 inches interference fit around the interfering cylindrical surfaces to provide a tensile hoop stress to hold the cap on the body.
