ABSTRACT:
A self-aligning, anti-cross threading fastener having a first member with lead threads having a curved surface feature from the minor diameter to the major diameter which allows the surface of the lead threads to cam over the mating threads of a second member and thereby aligning collinearly the longitudinal axis of the two members. The initial presentation angle of the two threaded members may be restricted and therefore enhanced by providing a protruding diameter feature.
