DIN985 Nylon Insert Lock Nut

The DIN985 Nylon Insert Lock Nut (Gr4, surface coated with white zinc) is a high-performance anti-loosening fastener. The built-in nylon ring generates a significant friction force when the bolt is screwed in, preventing the nut from loosening due to vibration or impact. This product is coated with white zinc on the surface, giving it excellent corrosion resistance and a beautiful appearance. This locking nut produced by Jinghong Fasteners strictly complies with the DIN985, has high dimensional accuracy and strong reliability, and is widely used in occasions requiring high-reliability anti-loosening in automobiles, machinery, electronic equipment, etc.

The DIN985 nylon insert locking nut (Gr4, surface coated with white zinc) adopts a unique nylon ring embedding design. When the bolt is tightened, it generates uniform radial pressure, forming a lasting and reliable anti-loosening friction force. The Gr4 high-strength material undergoes precise heat treatment to ensure that the nut maintains stable mechanical performance after repeated assembly and disassembly. The surface coating of white zinc provides excellent corrosion protection, suitable for harsh environments such as humidity and high temperatures. Jinghong standard parts ensure product size accuracy and consistency through automated production processes, enabling them to maintain excellent locking effect even under high-speed vibration conditions, significantly extending the equipment maintenance cycle.
