Patent ID: 8282308

Claim:
An assembly comprising: an outer member having a bore; an inner member having an cylindrical outer surface and concentrically disposed in the bore of the outer member to define a radial gap between the bore and the outer surface; and a fastener located in the radial gap between the outer and inner members, the fastener comprising: a strip of flat material formed into a discontinuous ring having an axis, circumferential ends that define a circumferential gap therebetween, an inner surface and an outer surface, wherein the inner surface of the ring contacts the outer surface of the inner member; a plurality of apertures formed in and circumferentially spaced apart about the ring; a plurality of fingers integrally formed from the ring, each finger cantilevered from a respective one of the apertures and extending radially outwardly at a finger radial length relative to the axis such that a distal end of each finger engages an inner wall of the bore, wherein each finger is of a first outline and is produced by being punched from the strip so that each respective aperture differs in shape from the first outline; and a plurality of projections integrally formed from the ring, circumferentially aligned with and alternating with the fingers, and extending radially outwardly at a projection radial length relative to the axis that is shorter than the finger radial length such that, when a radial load is applied to the assembly which bends the fingers radially inwardly, the projections contact the inner wall of the bore.
