Abstract:
1. 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, said retention and alignment element comprising: a plurality of elongated polymeric protuberances applied to the first component by directing an air born resin powder stream to the cylindrical wall and curing the resin thereon, each protuberance having (i) a base adhering to the cylindrical wall along the entire length of the protuberance, (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 the free ends engage the shaft of the second component along substantially the entire length of the protuberances, 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.
