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. The proximal end portion of the ferrule having been positioned to be associated with the knob in an insertion direction along the fastener axis, and the head portion of the fastener having been inserted within the knob for engagement to the knob in the insertion direction. The engagement between the proximal portion of the knob and the head portion of the fastener is configured to resist axial movement of the knob relative to the fastener along the fastener axis, rotational movement of the knob relative to the fastener about the fastener axis, and pivotal movement of the knob relative to the fastener axis.
