Cold Heading To Manufacture Structural Nuts

The diameter range of our structural nuts are usually 3/8''~1-1/8'' (M10~M33). During the production, we will first select the wire carbon steel for our structural bolts and nuts. After pickling and cold drawing, connect one end of the wire steel to the feeding position of the cold heading machine. According to the mold in the cold heading machine, the corresponding Structural semi-finished product will be punched: there is a hole in the middle, and the shape is similar to the hexagon bolt nut, but no thread yet. The old-fashioned cold heading machine cannot be formed at one time. After the Structural hexagonal semi-finished product is laid, it must be poured into the hopper on the tapping machine for tapping. If required, heat treatment (changing the hardness of the nut) and surface treatment (rust prevention) can also be conducted to perfect the structural steel bolts and nuts.
