Abstract
An electronic article surveillance tag is claimed wherein the tag features a spindle assembly which anchors and retains a set of ball bearings which are used to clutch and retain the shaft of a tack. The spindle features an operational tab which may be contacted by the appropriate probe to turn the spindle about a central axis. The spindle is seated in a retaining means with a graduated lip around the perimeter. The turning of the spindle serves to raise a portion of the spindle from the retaining means, loosening the ball bearing grip on the shaft of the tack. The electronic article surveillance tag may be used with either a smoothed or grooved tack shaft and may be operated by either mechanical probe actuation or by the use of a magnetic detachment means applied to the spindle.
