摘要: The screw comprises a circular thread portion 2a formed in a base portion of the screw, in which a helical thread is formed at the same depth and at the same crest angle; a special non-circular thread portion 2b which follows the portion 2a and has its thread depth gradually vary so as to assume a polygonal shape in cross section and permit the crest portion of thread to reach its highest points A-J in a turn of the thread, the highest points A-J being equal in thread depth and crest angle to the thread of the portion 2a; the portion 2b has its crest angle gradually increase as the thread moves from the highest points A-J to its lowest points along the length of the thread; and, lines connecting axially adjacent ones of the highest points A-J are tilted from the axis of the screw at a predetermined angle so that the portion 2b assumes a twisted polygonal prism-like shape as a whole.
