When it comes to industrial fasteners, hot dip galvanized bolts stand out as a critical component for durability and corrosion resistance. These fasteners are engineered to meet stringent standards while offering versatility across diverse applications. This article explores the features, specifications, and applications of high-strength hot dip galvanized bolts, along with insights into the company behind this innovation.

Product Overview

Hot dip galvanized bolts are a type of high-strength fasteners coated with a layer of zinc through a hot-dip galvanizing process. This coating provides exceptional protection against corrosion, making them ideal for use in harsh environments. The bolts are available in multiple grades, including 8.8, 10.9, and others, catering to varying strength requirements. Their design adheres to international standards such as ISO, DIN, ANSI, and ASTM, ensuring global compatibility and reliability.

Key Features and Advantages

Hot dip galvanized bolts offer a combination of strength, durability, and corrosion resistance. Here are some of their standout features:

• High Strength: Available in grades such as 8.8 and 10.9, these bolts are designed for heavy-duty applications requiring exceptional tensile strength.
• Corrosion Resistance: The zinc coating provides long-term protection against rust and environmental degradation, making them suitable for outdoor and industrial use.
• Customizable Options: Bolts can be tailored to specific dimensions, including lengths from 40mm to 6000mm and diameters ranging from M6 to M60.
• Compliance with International Standards: Adherence to standards like ISO 4017, DIN 933, and ASTM ensures interoperability and quality assurance.

Technical Specifications

Applications

These bolts are widely used in industries where strength and corrosion resistance are critical. Key applications include:

• Construction: For structural steel connections and outdoor infrastructure.
• Manufacturing: In machinery and equipment assembly where durability is essential.
• Marine: For shipbuilding and offshore platforms due to their resistance to saltwater corrosion.
• Automotive: In vehicle frames and components requiring high tensile strength.
