  • Captive fastener and method of assembling the same
    Patent number: 12203500
    Abstract: A captive fastener attachable to a panel along a fastener axis is provided. The captive fastener includes a fastener having a head portion and a shaft extending from the head portion and along the fastener axis. The captive fastener also includes a knob having a proximal end portion engaged to the head portion of the fastener and an annular portion extending radially around the fastener axis and the shaft of the fastener. A ferrule is associated with the knob, the ferrule defining an opening extending along the fastener axis and receiving the shaft of the fastener. The ferrule has a proximal end portion configured to prevent separation of the knob from the ferrule along the fastener axis and a distal end portion configured for engagement to the panel. A spring is positioned to bias the knob or the fastener proximally relative to the ferrule and to inhibit tilting of the knob or the fastener relative to the fastener axis.
