This product is used for automobile.
Its original craft was turning processing with high cost, and slow processing speed. Now It's changed to cold-forming semi-finished products, leaving a certain amount of turning processing, which helps to reduce costs and accelerate progress.

Besides, it is very difficult for rolling thread and knurl, and it requires a considerable level of work.
