Abstract

PURPOSE: To provide screw thread objects with flexibility and make possible to estimate their strength highly by producting the screws by press forming or extrusion.
CONSTITUTION: Helical surfaces 1 and 2 each formed on the upper and lower ends are congruous surfaces which can be overlapped one over the other and one pitch of their screw advance distance is formed to P. The thickness of a helicoid 3 which fills a space between the helical surfaces 1 and 2 is uniform at each point on the helical surfaces and formed equal to one pitch P. When a radius R which passes the rotating axis 0 of the helicoid 3 and the helical surfaces 1 and 2 turns one revolution, a starting point 4 and a terminal 5 form an end face 6 which has a width p in the direction of the axis 0 and is along the screw advance direction, because one screw advance distance of the radius is P. Thus, a disc shape screw thread object can possess flexibility and further its strength can be estimated highly.
