Screws are used in many industries in our lives. Among them, non-standard screws occupy most of them, while ordinary screws occupy a small part. Many people will ask why non-standard screws are more expensive than ordinary screws. What is the difference between the processing flow of standard screws and ordinary screws, you will understand after reading this.

Ordinary screw processing process: equipped with standard molds and heavy heads, it can be made directly by the machine. The processing process is relatively simple. If there are molds and punches, they can be punched out by directly loading the material, and then the hexagonal punch is used for thread rolling. And electroplating, you can leave the factory after finishing.

Non-standard screw processing process: Non-standard screw is a kind of non-standard screw. It appears because it is used on some machines or household items, and its processing process is different from ordinary screws. Many non-standard screws cannot be directly driven by a screw machine. They have to be processed by lathes, machine tools and other machines. The pcm rotary tool holder has a much longer processing flow than ordinary screws. Of course, after the non-standard screws are processed, the electroplating method of the European standard screw punch is similar to the ordinary electroplating method.

The difference between non-standard screws and ordinary screws is not only in processing, because the difficulty of the processing process also determines the price difference between the two.
