Hardlock Nut is composed of two upper and lower type self-tightening nuts, the upper nut has a bevel and the lower nut has a groove. When the two nuts are locked, the bevel and groove bite each other to form a conical structure.
This structure makes the Hadlock nut have a very strong anti-loosening performance, even in high-speed operation, severe vibration, temperature change and other harsh conditions, will not loose. This is very important for the high-speed rail, because the high-speed rail needs to withstand huge pressure and friction, if the nut is loose, it will cause the rail deformation or fracture, causing serious consequences.
Therefore, when China introduced Japan's "Shinkansen" technology in 2004, Hadlock nuts were introduced as one of the important components and were widely used on China's high-speed rail tracks. According to statistics, there are about 50 million Hardlock nuts used on China's high-speed rail tracks, accounting for 42% of the global market, which is enough to show that its performance is internationally recognized.
