ANTI-CROSS THREADING FASTENER

摘要

A self-aligning, anti-cross threading fastener (10) having first and/or seco nd members with lead threads (24) having a curved surface feature from the mino r diameter to the major diameter which allows the surface of the lead threads to cam over the mating threads of the other member (22) and thereby aligning collinearly the longitudinal axis of the two members. The initial presentati on angle of the two threaded members may be restricted and therefore enhanced b y providing a protruding diameter feature (18).
