Product Overview

**Hot-dip galvanized hex bolts** are a specialized type of fastener engineered to combine the mechanical strength of **Grade 8.8 carbon steel** with the protective properties of a **hot-dip galvanized coating**. This combination ensures durability in both indoor and outdoor environments, making them ideal for applications in construction, infrastructure, and heavy machinery.

The **LongZe** product line includes **hex bolts** in a wide range of sizes, from **M6 to M60** (1/4" to 2-1/2"), with customizable lengths up to **6000mm**. The bolts adhere to multiple international standards, including **ISO, DIN, ANSI, ASME, ASTM, and BS**, ensuring compatibility with global manufacturing requirements.

Key Features and Advantages

1. Exceptional Strength and Durability

**Grade 8.8** carbon steel provides **high tensile strength** (800 MPa) and **yield strength** (640 MPa), making these bolts suitable for high-load applications. The **hot-dip galvanizing process** further enhances their resistance to corrosion, extending their lifespan in aggressive environments.

2. Corrosion Resistance

The **hot-dip galvanized coating** forms a protective zinc layer that shields the steel from moisture, chemicals, and atmospheric exposure. This is particularly critical in **marine environments, coastal regions, and industrial zones** where rust is a common issue.

According to the **National Institute of Standards and Technology (NIST)**, galvanized coatings are widely recognized for their effectiveness in **preventing corrosion in steel structures** (NIST, 2025). This aligns with LongZe’s commitment to delivering **long-lasting solutions** for industrial applications.

3. Versatile Applications

These bolts are used in a variety of sectors, including:

• **Construction** (steel frame assemblies, bridge components)
• **Manufacturing** (machinery, equipment assembly)
• **Infrastructure** (highway signs, utility poles)
• **Agriculture** (equipment and storage structures)

4. Customization Options

LongZe offers **customizable sizes, lengths, and surface finishes** to meet specific project requirements. Options include **black oxide, zinc plating, and Teflon coatings**, providing flexibility for different environmental and aesthetic needs.
