U-Nut(FUJISEIMITSU) : As you tighten, the friction ring will ground to the bolt threads. From there, the friction ring begins to flex along the threads and press down on the bolt thread surface. The prevailing torque (friction torque) that is generated by the force (stress) of the spring returning and the force (reaction force) pulling the screws of the bolt and nut works. This serves as an anti-loosening function.
