Abstract
A bushing includes an upper collar with a lower sheath and an annular shoulder intermediate the collar and sheath. The collar has a plurality of spaced apart notches and the sheath has a plurality of spaced apart slits that may be circumferentially aligned with the notches. The sheath has a plurality of spaced apart ribs projecting outward circumferentially offset from the slit for assisting in maintaining the sheath within a hole in a fastener with the annular shoulder against the fastener. A securing member with an elongate shank extending from a head with a distal portion is maintained in the longitudinal opening in an upright position aligned with the hole. As the fastener is driven longitudinally through the opening and hole, force from the fastener causes the bushing to break away and yields direct contact between the securing member head against the top surface of the fastener.
