    摘要： This invention provides a bolt having threads that performs anti-loosening function and that maintains a specified thread strength, a bolt that also enables manufacturing costs to be reduced. The thread of the step lock bolt is constructed so to include a play side flank formed having a specified lead angle and a pressure side flank formed into a step like configuration, in which a flat portion whose lead angle is 0 (zero) and an inclined portion whose lead angle is steep alternate continuously.

    摘要： The invention presents a method of manufacturing a multi-pitch screw having desired threads and pitches by rolling. A trace of general (even lead angle) spiral screw is formed by even pitch protrusions 610 and 620 of an existing rotating dies 61 and 62, and it is combined with a trace of stair step screw formed by stair step protrusions 632 of a rotating die 63 of uneven lead angle, and multi-pitch screw threads are formed efficiently. Herein, only one rotating die 61 of uneven lead angle is used, and screw threads are not flattened out by stair step protrusions of the plurality of rotating dies of uneven lead angles.

    摘要： To present a method of manufacturing a multipitch screw easily by using flat dies suited to mass production. A flat die 4 includes linear ordinary screw threads 40a, and multipitch screw threads 40b consecutive to the ordinary screw threads 40a, slightly shorter in height than the ordinary screw threads 40a, with both side walls formed alternately and consecutively, alternating between a section departing from the central line 40c of screw threads and an approaching section along a central line 40c, and symmetrically to the central line 40c of screw threads. After forming the tacks of a constant lead angle screw on the outer circumference of a shaft-like blank piece by the ordinary screw threads 40a, tracks of a multipitch screw are formed by the multipitch screw threads 40b, and therefore the tracks of a multipitch screw varying in the force applied at the time of rolling can be formed easily.
