process of hex nuts

The manufacturing process of hex nuts mainly includes the following steps:

1. Material preparation: Select suitable materials, usually carbon steel, stainless steel, and other metal materials, and cut and process according to the required specifications and dimensions.
2. Cold heading forming: Place the cut material into a cold heading machine, press the material into a hexagonal shape through cold heading forming, and punch a hole in the center.
3. Thread processing: Place the formed Hexagonal Nut into a thread processing machine and machine the thread through cutting or rolling on the inner and outer surfaces.
4. Heat treatment: Heat treat the processed hexagonal nut to improve its strength and toughness.
5. Surface treatment: Conduct surface treatment on hex Nuts, such as galvanizing, chrome plating, etc., to improve their corrosion resistance and aesthetics.
6. Inspection and Packaging: Strictly inspect the manufactured hex nuts, including dimensions, threads, hardness, and other aspects, and then package and mark them.
