Nylock-Mutter

Willkommen bei der Nylock Nuts Kategorie unter MJ-Moderator (Hebei DuoJia Metal Products Co., Ltd.), your premier manufacturer and global supplier located in Handan Yongnian, the heart of China’s fastener production industry. Drawing on the technical expertise of our predecessor, the Yonghong expansion screw factory, we produce a comprehensive range of nylon insert lock nuts—including DIN 985 (Low Profile) und DIN 982 (High Profile) standards—specifically engineered for superior vibration resistance and self-locking performance in dynamic structural environments. Our nylock nuts feature a specialized internal nylon collar that deforms over the mating bolt threads, creating intense friction that prevents loosening under mechanical stress, thermal expansion, or repetitive impact. Precision-manufactured to comply with rigorous international standards, including GB, DIN, ANSI und BS, these fasteners are essential for automotive assemblies, heavy machinery, and high-load construction projects. Fabricated from high-grade Kohlenstoffstahl oder Edelstahl (SS304/SS316), they are available in various strength grades, ranging from Class 6 and 8 to 10, to handle demanding industrial load requirements. To guarantee long-term durability and protection against environmental corrosion, our products feature professional surface treatments such as White Zinc Plating, Yellow Zinc Plating, and Chrome Plating. With our advanced factory-direct production lines, we support Sonderanfertigung for non-standard thread pitches, specialized nylon insert colors, and unique material specifications based on your specific technical drawings. MJ Anchor is committed to providing reliable, laboratory-tested fastening components that meet the safety and precision demands of modern global infrastructure.
