ABSTRACT:
An improved, thin walled fastener for retaining studs, rods, or the like is provided. The fastener is of the push-on type comprising a one-piece, generally thin, stamped sheet metal resilient body defining a generally centrally located stud retaining aperture for receipt and retention of studs, rods or the like. The body is preferably generally frusto-conical or dome shaped in cross section. The fastener is formed by punching or shearing a hole in a blank and then forming a generally dome shaped impression in the blank, the impression being generally coaxial with the axis of the punched hole. The required transverse extensions of the body are minimized by the utilization of the relatively smooth continuous edge of the punched hole rather than the burred edge of a punched hole as the stud retaining edge of the fastener stud retaining aperture.
