ABSTRACT:
A jack extension tube for use on power seat adjuster mechanisms for vehicles is provided comprising an elongated tube having a first section and a second section spaced from the first section. A threaded member includes a knurled outer surface and is frictionally retained in the first section by inwardly extruding the tube onto the threaded member, the threaded member being engageable longitudinally from one end of said tube by a jack screw. The second section of the tube includes a pair of transversely oriented opposing apertures formed in the tube sidewalls and adapted to receive a pin-like member or fastener. The material defining the apertures is extruded in the transverse direction followed by collapsing the tube sidewalls so that the opposing flanges abut one another. Thus, the flanges provide a continuous, enlarged, work-hardened bearing surface to support the pin-like member or fastener.
