The HARDLOCK nut, developed by Japan's "Hardlock Industries" in 1974, consists of an upper nut with a bevel and a lower nut with a groove. It has extremely strong anti-loosening performance and will not loosen under harsh conditions such as high speed, vibration, and temperature difference.Due to its ability to withstand huge pressure and friction, it was introduced into China along with Japan's Shinkansen technology in 2004 and is widely used in high-speed rail tracks.
