1. A conic threaded fastener comprising: a body comprising at least one substantially conic outer surface; and at least one conic thread forming a spiral about said at least one substantially conic outer surface of said body such that said at least one conic thread forms a plurality of crests and a plurality of roots; wherein a tangential angle formed by an intersection of a plane coincident with a tangent line extending perpendicular from a line tangent to a point on one crest of said at least one conic thread to a point on an adjacent crest of said conic thread and a plane perpendicular to an axis of said body increases as a diameter of said outer surface of said body decreases; and wherein a tangential distance measured along said tangent line between said one crest of said at least one conic thread and each adjacent crest is substantially constant.
