The Yellow Zinc Nylon Lock Nuts, compliant with DIN982 and DIN985 standards, are advanced fasteners engineered for outstanding vibration resistance in rigorous industrial settings. These hex nuts utilize a nylon insert to produce prevailing torque, creating friction that secures them against loosening in high-vibration scenarios like machinery operations or vehicle suspensions. Constructed from premium carbon steel in grades 4.8 to 12.9, with stainless steel options (304/316) for environments with moisture or chemicals, the yellow zinc plating offers a vibrant, rust-resistant coating that enhances visibility and durability. Available in metric sizes M4 to M24 with coarse and fine thread choices, these nuts are produced by Duojia in Hebei, China, meeting ISO9001, ISO14001, and ISO45001 certifications for quality and sustainability. Ideal for automotive chassis, outdoor structures, and heavy equipment, they provide dependable fastening solutions that minimize maintenance and ensure long-term stability. With a production capacity of 10,000 pieces monthly and customizable packaging options, these yellow zinc-plated lock nuts cater to global demands, supporting efficient installations in construction, manufacturing, and beyond, while delivering excellent value through robust performance and corrosion protection.
Designed with a focus on reliability, the Yellow Zinc Nylon Lock Nuts feature a built-in nylon ring that engages bolt threads to deliver consistent torque and prevent vibrational loosening in applications such as automotive and industrial machinery. The yellow zinc galvanization applies a protective, golden-hued layer that resists corrosion, abrasion, and fading, making it suitable for exposed or outdoor use where aesthetics and longevity matter. Offered in DIN982 thin-hex and DIN985 heavy-hex variants, they are made from carbon steel or stainless steel, with thread pitches from 0.8mm to 3mm across sizes M5 to M24. Duojia’s rigorous testing for hardness and zinc thickness ensures product integrity, backed by SGS certification. For installation, hand-thread the nut until the nylon insert contacts, then torque with a wrench, avoiding over-tightening to maintain insert effectiveness. Outdoor inspections should check the coating for scratches, repairable with rust-proof paint. With minimum orders of 100 pieces and 14-30 day delivery, these nuts are packaged in cartons or pallets for secure transport. Exported worldwide to regions like Asia, Europe, and the Americas, they offer a versatile, high-quality option for secure fastening needs.

Equipped with a nylon insert for effective torque generation, the Yellow Zinc Nylon Lock Nuts excel in maintaining secure connections under constant vibration, such as in automotive suspensions or industrial machines. The yellow zinc finish provides a distinctive golden color that improves visibility for safety checks while offering strong resistance to rust and environmental wear. Built from carbon steel in high-strength grades or corrosion-resistant stainless steel, these nuts feature accurate metric threading from M4 to M24, accommodating coarse or fine pitches for precise fits. Duojia’s green manufacturing practices, supported by ISO standards, include comprehensive quality tests for durability and coating adhesion. Customizable elements like thread variations and finishes allow adaptation to specialized needs. Their design safeguards against over-torquing, preserving the nylon’s integrity for repeated use, and the lightweight structure supports high loads without adding excess weight. This combination of features ensures enhanced performance in visible applications, where the bright plating aids identification, making them a preferred selection for professionals requiring dependable, low-maintenance fasteners with superior anti-loosening properties.
Yellow Zinc Nylon Lock Nuts are highly versatile for applications needing vibration resistance and visible corrosion protection across various sectors. In automotive industries, they secure chassis components and suspension systems, ensuring stability on rough terrains where vibrations are constant. Construction projects utilize them for fastening metal structures and outdoor fixtures, benefiting from the yellow coating’s rust resistance in weather-exposed environments. Industrial machinery, including pumps and conveyors, relies on these nuts to maintain tight connections amid operational shakes, reducing downtime in manufacturing plants. For marine and agricultural uses, they anchor equipment like boat rigging or farm implements, with stainless steel versions handling damp conditions effectively. Outdoor metal assemblies, such as fencing or signage, leverage the golden hue for easy spot-checks and long-lasting hold. Duojia’s products, exported to countries including Australia, Germany, and Thailand, support custom installations with simple maintenance protocols, like periodic nylon wear inspections and coating repairs. This adaptability makes them suitable for both heavy-duty tasks and general projects, promoting safety and efficiency in dynamic settings worldwide.
