To standardize the high-end fastener market and improve the quality of essential components for the manufacturing industry, the Standardization Administration of China recently launched the revision of two national standards: "Elastic Lock Nuts" and "Plastic Clip Fasteners." Type A spring nuts and U-shaped clips will be officially included in the technical specifications.
Preventing loosening of components is crucial in safety-critical applications such as high-speed rail and subway systems. CRRC Corporation Limited recently implemented a combined "A-type spring nut + U-shaped clip" fastening solution in several projects. This solution is applied to key areas such as car connectors, electrical cabinets, and air conditioning systems, providing the dual security of "mechanical locking and wiring harness retention."
Amid the accelerating development of new energy vehicles, the reliability and efficiency of wiring harness fastening systems are attracting significant attention. Recently, U-shaped clips, due to their ease of installation, strong vibration resistance, and light weight, have gradually replaced traditional cable ties and metal clips as the preferred solution for securing wiring harnesses in key areas such as battery packs and motor controllers.
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.
