The DIN 985 Nylock Nut, featuring white zinc plating on carbon steel, represents a high-performance locking fastener designed to resist loosening in vibration-intensive environments. This heavy-hex prevailing torque nut includes an internal nylon insert that creates friction with bolt threads, ensuring secure clamping in applications such as automotive assemblies and industrial machinery. Produced from durable carbon steel in grades 4.8 to 12.9, with stainless steel options like A2-70 and A4-80 for added corrosion resistance, the white zinc coating provides a bright, protective layer against rust and wear. Available in metric sizes from M4 to M24, with coarse and fine thread options, these nuts are manufactured by Duojia in Hebei, China, adhering to ISO9001, ISO14001, and ISO45001 standards. They support heavy and general industry uses, offering reliable performance for construction, marine, and equipment fastening needs. With a monthly supply of 10,000 pieces and flexible packaging, these white zinc-plated nylock nuts deliver cost-effective solutions for maintaining stability and safety in dynamic settings, backed by SGS certification and global export capabilities.
Engineered for precision, the DIN 985 Nylock Nut incorporates a nylon ring that engages bolt threads to generate prevailing torque, effectively preventing self-loosening under vibrations from engines or heavy tools. The white zinc plating, applied through galvanization, forms a resilient barrier against corrosion, suitable for both indoor and outdoor exposures with its clean, reflective finish. Made primarily from carbon steel, with stainless steel alternatives available, these nuts come in sizes M4 to M24 and feature detailed thread pitches ranging from 0.8mm to 3mm. Duojia’s quality assurance includes hardness testing and zinc thickness checks, ensuring consistent reliability. Installation involves hand-screwing until the nylon contacts the threads, followed by wrench tightening without excess force to avoid insert damage. Regular inspections for wear and coating integrity are recommended, with repairs using zinc-rich paint if needed. Offered with minimum orders of 100 pieces and delivery in 14-30 days, these nuts are packaged in cartons, bags, or pallets for efficient shipping. Exported to markets worldwide, including Europe, Asia, and the Americas, they provide a dependable fastening option for professionals seeking long-term durability.

These DIN 985 Nylock Nuts are distinguished by their nylon insert, which delivers effective locking through friction, ideal for countering vibrations in machinery and vehicles. The white zinc plating enhances corrosion resistance while providing a smooth, bright surface that facilitates easy handling and visual checks. Constructed from carbon steel in various grades for superior strength, or stainless steel for harsh environments, they offer precise metric threading in sizes M4 to M24 with options for coarse or fine pitches. Duojia’s environmentally conscious production, supported by ISO certifications, includes rigorous testing for hardness and coating quality. Customizable features allow for tailored thread designs and finishes to meet specific requirements. Resistant to over-tightening, these nuts maintain torque without compromising the insert, and their robust design ensures high load capacity in compact forms. The white finish not only protects against oxidation but also improves aesthetics in visible applications, making them a versatile choice for engineers focused on reliability and ease of maintenance in fastening systems.
DIN 985 Nylock Nuts with white zinc plating are essential in applications demanding secure, vibration-resistant fastening across multiple industries. In construction, they lock structural components in buildings and bridges, where movement from wind or machinery requires dependable hold. Automotive uses include securing parts in engines, transmissions, and suspension systems, ensuring safety during high-speed or off-road operations. Industrial equipment benefits from their application in pumps, conveyors, and assembly lines, with the corrosion-resistant coating suited for factories with moisture or chemicals. Marine environments utilize them for deck fittings and rigging, leveraging the zinc protection against saltwater. In agriculture, these nuts fasten implements on tractors and harvesters, maintaining integrity under field vibrations. They also support general uses like furniture manufacturing and electrical enclosures for stable mounts. With Duojia’s global reach to countries such as Russia, Germany, and Australia, these nuts facilitate efficient installations, easy replacements for worn parts, and compliance with safety standards, enhancing productivity in both heavy-duty and everyday projects.
