High-Strength Bolts for Heavy-Duty Applications | Hengke Metal

A staple in the product range of Pinghu Hengke Metal Products Factory—Jiaxing’s professional fastener manufacturer and exporter near Shanghai, Zhapu, and Ningbo ports—the bolt zinc plated series is designed to enhance corrosion resistance and extend product lifespan for global clients in Europe, the United States, and beyond. Our bolt zinc plated products undergo a high-quality zinc plating process, which creates a protective barrier against moisture, chemicals, and environmental factors, making them ideal for outdoor applications, automotive components, and industrial machinery—areas where we collaborate closely with major manufacturers. Each bolt zinc plated is tested for plating thickness and adhesion to ensure consistent protection, with additional quality checks for tensile strength and thread integrity to meet international standards. We offer a wide variety of bolt zinc plated options, including different head types (hex head, socket head) and sizes (metric and inch), to suit diverse project needs. Supporting OEM/ODM customization, our technical team can adjust the zinc plating process and bolt specifications to match specific customer requirements, providing expertise on application scenarios. Backed by 20+ years of production experience and a "quality first" approach, our bolt zinc plated products are exported globally, trusted for their durability, cost-effectiveness, and ability to withstand harsh conditions, making them a top choice for clients seeking reliable, corrosion-resistant fasteners.
