Abstract
A threaded fastener that self locks as it is tightened to a fastened object. The thread includes one or more portions that are shifted, resulting in one or more discontinuities in the thread. Each shifted portion of thread is fully formed at the discontinuity. The shifted portions will deform a relatively softer female thread, causing the deformed thread to move up and over the end faces of the shifted portions and to pack up in front of the end faces to prevent any significant loosening of the connection.
