Zinc-Nickel Alloy Coated Carbon Threaded Rod Bolts with Nuts are high-performance fastening solutions designed for superior corrosion protection in demanding environments. These fasteners combine the strength of carbon steel with a sophisticated zinc-nickel alloy coating, offering significantly enhanced corrosion resistance compared to traditional zinc platings. The threaded rod bolt design, paired with a matching nut, ensures a secure and robust connection, making them ideal for applications requiring long-term durability and resistance to harsh elements.

Definition

Zinc-Nickel Alloy Coated Carbon Threaded Rod Bolts with Nuts are carbon steel fasteners that feature a continuous threaded rod form, and are electroplated with a zinc-nickel alloy. This advanced coating, typically containing 12-15% nickel, provides exceptional cathodic and barrier corrosion protection, often surpassing standard zinc platings. These bolts are supplied with compatible nuts, forming a complete assembly engineered for high strength and extended service life in corrosive or high-stress applications.

Advantages

• Superior Corrosion Resistance: The zinc-nickel alloy coating offers significantly higher corrosion protection compared to standard zinc plating, especially against red rust, making them suitable for aggressive environments.
• Enhanced Durability and Longevity: Combines the inherent strength of carbon steel with the protective benefits of the zinc-nickel alloy, ensuring a longer service life and reduced maintenance.
• Sacrificial Protection: The zinc-nickel coating acts as a sacrificial layer, corroding before the base carbon steel, thereby protecting the underlying fastener from degradation.
• Hydrogen Embrittlement Resistance: Zinc-nickel coatings generally have better resistance to hydrogen embrittlement compared to other high-strength coatings, which is crucial for critical applications.
• High Temperature Performance: Maintains effective corrosion protection at elevated temperatures where standard zinc coatings can degrade.
• Environmentally Compliant: Often a preferred alternative to cadmium plating due to its similar performance in corrosion resistance but with reduced environmental impact.
• Consistent Performance: Provides reliable and consistent fastening performance even under challenging conditions.

Applications

• Automotive Industry: Widely used in critical components for vehicles, including chassis, engine parts, and braking systems, where high corrosion resistance is essential.
• Offshore and Marine Applications: Ideal for use in marine environments, on oil rigs, and in shipbuilding due to excellent resistance to saltwater and harsh weather conditions.
• Wind Energy: Employed in wind turbine construction and maintenance, particularly for components exposed to outdoor elements and varying climates.
• Infrastructure Projects: Suitable for bridges, tunnels, and other public infrastructure where long-term durability and resistance to environmental degradation are required.
• Heavy Machinery and Equipment: Used in construction equipment, agricultural machinery, and industrial plants for secure and durable fastening.
• Chemical Processing Plants: Provides resistance to various chemicals, making them suitable for fastening in processing equipment and pipelines.
• Electrical and Electronic Equipment: Can be found in outdoor electrical enclosures and components that require robust corrosion protection.
