The series of dual anti-loosening vibration-absorbing self-locking nuts produced by our company features several technical advantages, including self-locking performance of the upper and lower bodies, automatic tightening capability, bidirectional vibration absorption, dual anti-loosening properties, and repeatable use. These products are particularly suitable for threaded connections in harsh working conditions, such as heavy loads, high speeds, and large alternating vibration frequencies. They effectively address the issue of loosening connections across various industries, ensuring that once locked, they never loosen, regardless of the intensity of vibration. This results in maintenance-free or low-maintenance solutions, providing users with safe and reliable assurance while saving on maintenance costs. The overall anti-loosening performance of our products has reached an internationally leading level and has been recognized as a national high-tech product.

Our anti-loosening nuts have been applied in fields such as the State Grid’s ultra-high voltage transmission and distribution lines, electrified railways (high-speed rail), urban rail transit, military products, ships, vehicles, and wind power.
