Abstract:
A fastener sized and shaped so as to be adapted to secure an elongate rod within a rod receiving member wherein the rod has a rod axis and a rod surface and the receiving member has a threaded bore; said fastener comprising:(a) a first shaft segment having a fastener axis and a first radius with a threaded outer surface adapted to be threaded into said threaded bore about an axis of rotation; (b) a second shaft segment having a second radius of a smaller size than said first radius and extending coaxially from said first shaft segment; (c) said first shaft segment being rigid and shaped bore to be rotatably received within the so as to retain said first shaft segment therein with said second shaft segment extending outwardly from the bore; and (d) said fastener being sized and shaped so that when said shaft first segment is fully received in said bore, said second shaft segment second radius is sized such that said second shaft segment interferingly engages said rod surface along a substantial segment thereof to thereby inhibit rotation of said rod about said rod axis and translation of said rod along said rod axis relative to the receiving member.
