| 主权项 | 1. A method of manufacturing an internal thread of a nut configured to be used in a screw-and-nut system, the method comprising: forming the internal thread in the nut with a material removal stage, a nominal diameter value of the internal thread being less than a predetermined final nominal diameter value, and after forming the internal thread, during a plastic deformation stage, displacing material of the internal thread formed during the material removal stage to obtain the predetermined final nominal diameter value, the method including forming a groove on the internal thread during the material removal stage. | ||
