Description

technical field [0001] The invention relates to the technical field of nut preparation, and mainly relates to a double-thread nut and a preparation process thereof. Background technique [0002] A nut is a nut, a part that is screwed together with a bolt or a screw for fastening. A component that must be used in all manufacturing machinery is divided into carbon steel, stainless steel, and non-ferrous metals (such as copper) according to different materials. several types. [0003] The existing nut is convenient to use by setting the inner center as a thread, and then setting the outer part into a corresponding shape according to requirements. [0004] However, nowadays people want to use the nuts for the feet of the handrails of the stairs for corresponding use, so that the nuts are connected with the handrail nuts, and then the nuts are connected with the screws on the ground, so that it is easy to operate and convenient for later replacement, so this The operation, that...
