my country has achieved another success in the field of high-end precision fasteners. Recently, a precision hardware company in Jiangsu successfully developed a high-performance "A-type spring nut." The product has passed 2,000 hours of salt spray testing and 100,000 cycles of vibration fatigue testing, reaching internationally advanced performance levels and achieving domestic substitution.
The A-type spring nut is a self-locking, elastic nut widely used in equipment subject to high vibration environments, such as engine mounts, industrial robots, and new energy electronic control boxes. Its unique structure automatically locks after the bolt is tightened, preventing loosening and significantly improving connection reliability.
Previously, this product had long been imported from Germany and Japan. This domestic production breakthrough not only reduced procurement costs by over 30% but also shortened delivery cycles. The product has already secured bulk orders from several leading equipment manufacturers, marking a key step forward for my country in the field of high-end anti-loosening fasteners.
