Abstract
A captive fastener is disclosed having a longitudinal slot along the shank for receiving a hold-out clip, and a chamber that houses a retractable push out pin. The push out pin is spring actuated to extend out of the shank and can be retracted into the cavity against the bias of the spring to pass through a primary panel and subpanel. The push out pin is shaped to bear against a counterbore and secure the fastener within a panel while other components are affixed to the fastener.
Claims6
A captive fastener having a head, a neck, and a threaded shaft, the fastener further comprising:
- an elongate longitudinal slot along the threaded shaft retaining a cantilevered hold-out clip having a distal end extending outside the elongate longitudinal slot in an absence of a radially inward force and said distal end including a tip portion curved toward said elongate longitudinal slot such that contact with a surface normal an axis of said shaft directs the hold-out clip fully inside the elongate longitudinal slot, the elongate longitudinal slot sized to enclose the hold-out clip entirely therein;
- and
- an extendable push out pin disposed within a chamber in the threaded shaft, the extendable push out pin including a compression spring biasing the extendable push out pin radially outward from the chamber to extend out of the shank, the chamber sized to receive the extendable push out pin fully within.
