The Black Zinc Nylon Lock Nuts, adhering to DIN982 and DIN985 standards, are premium fasteners designed for superior vibration resistance in high-stress environments. These hex nuts incorporate a nylon insert that creates essential friction with bolt threads, preventing loosening in applications like heavy machinery and automotive assemblies. Made from robust carbon steel in grades 4.8 to 12.9, with stainless steel alternatives (304/316) for corrosion-prone areas, the black zinc plating delivers excellent rust protection and a durable, matte finish. Ideal for industrial settings, these nuts come in metric sizes M4 to M24, supporting both coarse and fine threads for versatile compatibility. Manufactured by Duojia in Hebei, China, they meet ISO9001, ISO14001, and ISO45001 certifications, ensuring quality and environmental compliance. With a supply capacity of 10,000 pieces per month and options for bulk packaging, these vibration-resistant lock nuts provide reliable performance for construction equipment, off-road vehicles, and manufacturing fixtures, reducing the risk of failure and enhancing overall system stability in demanding operations.
Crafted with precision, the Black Zinc Nylon Lock Nuts feature a nylon ring that engages upon installation, generating prevailing torque to secure connections against vibrations from engines or industrial tools. The black zinc galvanization process applies a protective layer that resists wear, oxidation, and environmental damage, extending the nut’s lifespan in harsh conditions. Available in DIN982 thin-hex and DIN985 heavy-hex designs, they are produced from carbon steel or stainless steel, with detailed specifications including thread pitches from 0.8mm to 3mm across sizes M5 to M24. Duojia’s production includes advanced testing for hardness and zinc thickness, guaranteeing consistency and reliability. Installation is straightforward: hand-tighten until the nylon insert contacts the threads, then use a wrench for final torque, avoiding excessive force to preserve the insert. These nuts support heavy-duty uses, with minimum orders starting at 100 pieces and delivery within 14-30 days. Packaged in cartons, bags, or pallets, they are exported globally to markets in Europe, Asia, and the Americas, making them a trusted choice for professionals needing dependable anti-loosening fasteners.

These Black Zinc Nylon Lock Nuts stand out with their integrated nylon insert, which provides reliable locking action by creating friction that counters vibrational forces in machinery and vehicles. The black zinc finish offers robust protection against rust and abrasion, ensuring longevity in outdoor or industrial exposures. Constructed from high-grade carbon steel or stainless steel, they deliver impressive tensile strength across various grades, with precise threading for secure fits in sizes M4 to M24. Duojia’s eco-friendly manufacturing process, backed by ISO certifications, emphasizes quality control through hardness and coating tests. Customizable options include specific thread types and coatings, catering to unique engineering needs. Their design prevents over-tightening damage while maintaining torque integrity, and the matte black appearance aids in visual inspections. Lightweight yet strong, these nuts reduce assembly weight without compromising on load capacity, making them suitable for dynamic applications where regular maintenance is key to preserving performance.
Black Zinc Nylon Lock Nuts excel in diverse applications requiring vibration resistance and secure fastening. In heavy industry, they are used to lock components in construction equipment like bulldozers and cranes, where constant motion demands anti-loosening reliability. Automotive sectors apply them in engine mounts, suspension systems, and chassis assemblies for off-road and commercial vehicles, ensuring stability on uneven terrains. Manufacturing environments benefit from their use in conveyor belts, robotic arms, and assembly lines, with the corrosion-resistant coating ideal for factories with humidity or chemical presence. In marine settings, stainless steel versions secure rigging and deck hardware against saltwater and movement. Agricultural machinery, such as plows and harvesters, relies on these nuts for durable connections under field vibrations. They also find use in electrical enclosures and furniture production for vibration-prone installations. With global distribution and proven effectiveness in regions like Europe and Asia, these nuts support efficient operations by minimizing downtime through easy replacement and consistent performance in both professional and custom projects.
