Claim:
A fastening system for securing a plurality of work pieces together, comprising: a bolt having an elongated shank adapted to be positioned within aligned openings in the work pieces, the shank terminating at one end in an enlarged head and including a threaded portion having a plurality of external bolt threads, the bolt threads of the bolt including a plurality of crests and a plurality of roots, each of the plurality of roots including a root radius, each of the plurality of crests being joined to a corresponding one of the plurality of roots by a first bearing flank and to a corresponding another of the plurality of roots by a second bearing flank opposite the first bearing flank, each of the first and second bearing flanks including a first tangential radius and a second tangential radius, wherein the first tangential radius extends from the corresponding one of the plurality of roots of the bolt threads to the second tangential radius, and the second tangential radius extends from the first tangential radius to the one of the plurality of crests, each of the plurality of crests including a flat surface extending between the second tangential radius of the first bearing flank and the second tangential radius of the second bearing flank, the bolt being made from a first material; and a nut having a plurality of internal nut threads, the nut threads defined by a plurality of crests and a plurality of roots, one of the plurality of crests of the nut threads being joined to a corresponding one of the plurality of roots of the nut threads by a bearing flank, -the nut threads being sized and shaped to threadedly engage the bolt threads, the nut being made from a second material that is softer than the first material of the bolt, whereby when the nut threads engage the bolt threads of the bolt, each of the second tangential radii of each of the first bearing flanks and each of the flat surfaces of the plurality of crests of the bolt threads is adapted to embed into a corresponding one of the plurality of bearing flanks of the nut threads and each of the plurality of crests of the nut threads is adapted to deform and flow into the root radius of a corresponding one of the plurality of roots of the bolt threads to create complete contact between the engaged nut threads and bolt threads so as to restrict the nut from moving in a direction transverse to a longitudinal axis of the bolt.
