Screw thread manufacture of nuts

M10 standard parts and screws are also manufactured from the circular line by a multi-stroke automatic die casting machine. The use of hexagonal lines instead of round lines can reduce the number of impact layers. Some nuts are manufactured using flat wire materials without ordinary casting methods such as transfer devices. When the diameter of the large nut specifications are M22~M36, steel rods are used on the material, and multiple punching layers are used to manufacture the pressed products. The thread of different nuts from the screw is cut by automatic tapping machine. So far, the technology of transforming nuts has not been very successful, and nut processing using tapping machines to cut without cutting layers is occasionally used.
