The manufacturing process of hexagon nuts

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

1. Material preparation: Select suitable materials, typically carbon steel, stainless steel, and other metal materials, and perform cutting and processing according to the required specifications and dimensions.
Cold heading molding: Put the cut material into a cold heading machine, press the material into a hexagonal shape through cold heading molding, and punch a hole in the center.
3. Thread processing: Put the formed hexagon nut into a thread processing machine, and process the thread through the inner hole and outer surface by cutting or rolling.
4. Heat treatment: Heat treat the processed hexagon nut to make it have better strength and toughness.
5. Surface treatment: Carry out surface treatment for hexagon nuts, such as zinc plating and chromium plating, to improve their corrosion resistance and aesthetics.
6. Inspection and packaging: Strictly inspect the manufactured hexagon nuts, including dimensions, threads, hardness, and other aspects, and then package and mark them.
