Product Description

GB5783 Class8.8 Zinc Galvanized Hex Head Bolt For Machinery


1.Products Details:

Hexagon head galvanized bolts are a type of fastener with a six-sided (hexagonal) head, designed for secure and reliable joining of components in various applications. They undergo a galvanization process—coating with a layer of zinc—to enhance their durability and resistance to environmental factors.


2.Key Features:

- Hexagonal Head Design:

Allows easy tightening and loosening using standard wrenches or sockets, ensuring efficient installation and maintenance.
- Galvanized Coating:

The zinc layer acts as a protective barrier, significantly improving corrosion resistance, making them suitable for outdoor, humid, or industrial environments where exposure to moisture, chemicals, or weathering is common.
- High Strength:

Typically made from carbon steel (e.g., 8.8 grade) or alloy steel, providing strong clamping force for structural and mechanical connections.
- Versatility:

Widely used in construction, automotive, machinery, electrical equipment, and infrastructure projects due to their compatibility with nuts and various materials (metal, wood, etc.).
- Cost-Effective Protection:

Galvanization offers long-term corrosion resistance at a relatively low cost compared to other protective treatments like stainless steel.
