  • Patent number: 6644903
    Abstract: A captive fastener for press-in installation in panels has a ferrule capable of being crimped to provide a positive engagement with a screw element of the captive fastener. The ferrule has a hardness gradient such that a penetration tip of the ferrule has a hardness greater that exceeds the hardness of the panel, and an upper rim of the ferrule is deformable to limit movement of the ferrule relative to the screw element by interference. Typically, the penetration tip has a hardness greater than about Rockwell B60 to permit the press-in installation to the panel.
