ABSTRACT:
A captive fastener for securing two closure members together comprises a crew component adapted to be affixed to one of the closure members and a complimentary nut component adapted to be affixed to the other closure member. The screw component comprises a housing, a drive sleeve disposed within the housing for rotational movement therein, and a screw member in operatinal engagement with the drive sleeve whereby the screw member is axially movable between extended and retracted positions relative to the housing in response to the rotational movement of the drive sleeve. The nut component comprises a shell, a nut member disposed within the shell for limited axial and radial movement therein and fixed against rotation, and biasing means for urging against the axial movement of the nut member. The radial and axial movement of the nut member facilitates the alignment and engagement of the screw member with the nut member to eliminate binding when the closure members are assembled. The screw component is designed so that the screw member is fully retracted upon disassembly and also to permit a flush-mounting with the closure member during operation of the fastener.
