ABSTRACT:
A threaded fastener has an eccentric tip with a smooth portion and a threaded portion. The smooth portion when viewed in side elevation defines an edge on a curve with an arcuate slope and the tip threaded portion is coincident with the shank to provide a threaded fastener which substantially eliminates axial and angular misalignment.
