By changing the shape of the thread, the Motiontite increases the amount of curvature to improve the fundamental elasticity of the bolt.
The structure of the screw has been changed to have an asymmetrically shaped thread with a summit of more than 60 degrees, and a large R shaped part which extends along the flank to provide pressure so that, when the screw and the flank face come into contact, the thread is elastically deformed.
Also, with a curved thread, the maximum load on the primary thread is distributed to other threads, relaxing the concentration of stress on the structure resulting from heavy loads.
