Abstract: A locking thread fastener for use in a mating part having a conventional internal thread where the thread of the fastener has a varying pitch distance along the length of the screw so that interference is encountered on the flanks of the thread when the fastener is driven into the mating part. The pitch distance varies in an oscillating manner between maximum and minimum values.
