Abstract
A fastener assembly including a retention and alignment element used in combination with a first component having a cylindrical wall defining a bore and a second component having an elongated shaft for insertion into the bore of the first component. The retention and alignment element comprises a plurality of elongated polymeric protuberances, each having (i) a base fixed to the cylindrical wall of the first component, (ii) a height sufficient so that together the free ends of the protuberances define a passageway that creates an interference fit with the shaft of the second component, and (iii) a length sufficient to maintain the shaft of the second component generally collinear with the axis of the bore of the first component.
