| High Light | Grade 12.9 carbon steel bolt ，Galvanized self-tapping metal bolt ，Yellow zinc plated hanger bolt | ||
Engineered for the most demanding fastening applications, this double hanger head metal bolt represents the pinnacle of strength within the carbon steel fastener family. Manufactured from premium alloy steel and subjected to rigorous quenching and tempering heat treatment, it achieves the Grade 12.9 property class, signifying a minimum tensile strength of 1200 MPa. This ultra-high strength makes it capable of withstanding extreme loads and dynamic stresses. The bolt features a specialized self-tapping thread design on one or both ends, allowing it to form its own mating threads when driven into pre-drilled holes in metal or hard materials, eliminating the need for pre-tapping. Available with a choice of high-performance coatings—GAL (Galvanized), standard Zinc Plated (ZP), or Yellow Zinc Plated—this bolt offers tailored corrosion protection for various environments. The "double hanger head" design provides a robust driving surface, ensuring positive engagement during installation.
| Industry | Usage |
|---|---|
| Automotive | High-strength applications in engines, heavy-duty machinery, and bridge construction |
| Mechanical | Connecting mechanical parts, circuit boards, engines, transmissions in various industries |
| Energy | Connecting power generation equipment and transmission lines |
| Architectural | Building structures, shipbuilding, and petrochemical equipment |
This ultra-high-strength self-tapping hanger bolt is specifically designed for heavy industrial, automotive, and structural applications where maximum clamping force and resistance to vibration are critical. It is commonly used in:
Heavy Equipment Assembly: Securing components in agricultural machinery, construction equipment, and mining vehicles where extreme loads and shock are routine.
Automotive and Truck Manufacturing: For chassis connections, engine mounting brackets, and suspension components that demand the highest strength fasteners.
Structural Steel Connections: In applications where a self-tapping feature is advantageous for joining thick metal sections without pre-tapping.
The choice of finish dictates the suitable environment:
Zinc Plated (ZP): Suitable for general industrial indoor use.
Galvanized (GAL): Provides a thicker zinc coating for improved outdoor durability.
Yellow Zinc Plated: Offers enhanced corrosion resistance compared to clear/blue zinc and provides a distinctive golden appearance, often used in automotive underhood applications.
The standout advantage is the Grade 12.9 strength rating, the highest standard property class for carbon steel bolts, ensuring unparalleled load capacity and joint security in the most demanding applications. The self-tapping thread design significantly reduces installation time and labor costs by eliminating the separate step of tapping holes, while also creating a tighter, more vibration-resistant fit due to the thread-forming process. The availability of multiple zinc-based finishes (ZP, GAL, Yellow Zinc) allows for precise specification based on the required level of corrosion protection and aesthetic preference. The robust double hanger head provides a positive, durable drive surface capable of transmitting the very high torques required to properly preload a Grade 12.9 fastener, ensuring the joint achieves its full strength potential.
