Abstract: A decorative cap and wheel nut or bolt insert, and a method of assembling them. The insert is coated and/or plated and includes a hex-shaped section and a section having a circular cylindrical outer surface. A cap includes a hex cross-section segment and a circular cylindrical cross-section segment. The hex cross-section segment of the cap slips easily over the hex section of the insert while the circular cylindrical cross-section segment has a smaller ID than the OD of the circular cylindrical insert section whereby an interference fit is formed between them when the insert is press fit into the cap.

The hex cross-section segment of the cap slips easily over the hex section of the insert while the circular cylindrical cross-section segment has a smaller ID than the OD of the circular cylindrical insert section. The cap is formed of sheet material which is both plastically and elastically deformable. When pressed onto the insert, the cap deforms both plastically and elastically. An interference fit is formed between them by radial plastic deformation of the cap.

Abstract: An improved capped wheelnut of the type including a nut body having a central threaded aperture and a pair of ends, one end being adapted to engage a wheel, and a cap for said nut body at the other end. The cap has an end wall and a continuous side wall which terminates intermediate the ends of said nut body in an annular edge, an insulating washer constructed of material having low heat conductivity, said washer being of annular ring shape and positioned on said nut adjacent the lower end of said cap, a portion of said cap being engaged with said washer so as to maintain said washer in engagement with said nut body so that it will not fall off the nut.
