Abstract
A fastener device is disclosed. The fastener device includes a hub defining a bore, an attachment shank including a proximal stop and distal bit received within the bore, a retainer releasably engagable with a proximal end of the hub and a defining a passageway for a proximal mounting end of the attachment shank, a biasing element engaged with the proximal stop, and a split cam assembly disposed within a distal end of the bore. The split cam assembly is biased toward a closed configuration for engaging and retaining the head of a fastener, and is pivotable upon distal advancement of the attachment shank and distal bit, against the head, to release the head from engagement with the split cam assembly.
