Product Overview

Hot dip galvanized bolts are a specialized type of hex bolt designed for high-strength applications. These bolts are coated with a hot-dip galvanized layer, which provides superior protection against rust and environmental degradation. The Grade 8.8 designation indicates their high tensile strength, making them ideal for demanding industrial and construction environments. Available in a wide range of sizes and materials, these bolts cater to global standards such as ISO, DIN, ANSI, and ASTM.

Key Features and Advantages

• High Strength: The Grade 8.8 rating ensures exceptional load-bearing capacity, suitable for heavy-duty applications.
• Corrosion Resistance: The hot dip galvanizing process creates a protective zinc layer, extending the bolt's lifespan in harsh environments.
• Compliance with Global Standards: Adherence to ISO, DIN, ANSI, and ASTM ensures compatibility across international projects.
• Customizable Sizes: Available in M6-M60 and lengths ranging from 40mm to 6000mm, accommodating diverse engineering needs.
• Material Versatility: Options include carbon steel, stainless steel, and specialized alloys like 40Cr and 20MnTiB.
