Xinxiang Xinhua Changling Machinery Factory   

Our company is specialized in manufacturing, selling, developing and designing steel threaded sets. It also produces matching taps, installation tools, special plug gauges. At present, our company adopts the most advanced wire rolling equipment in our country. The spiral coils with high strength, high accuracy and smooth surface are precisely formed by concentric rings of high precision internal and external threads. After forming the wire screw, a high precision internal thread that meets the corresponding standards is formed, and its performance is better than that of the internal thread formed directly by tapping.
