Grade 12.9 screws are ultra-high-strength fasteners made from SCM435 alloy steel, featuring a minimum tensile strength of 1220Mpa and hardness of 39-44HRC. These bolts are primarily used in textile, hydraulic, injection molding, and mechanical industries.
The black oxide treatment forms a protective oxide film on the metal surface, providing rust prevention while eliminating reflections. This treatment is particularly suitable when strict appearance requirements aren't necessary.
Flange bolts combine a hexagonal head with an integrated flange, offering a larger support area than standard bolts. This design enables higher preload capacity and superior anti-loosening performance, making them ideal for automotive engines and heavy machinery applications.
| Industry | Usage |
|---|---|
| Automotive | Essential for high-strength applications including automotive engines, heavy-duty machinery, and bridge construction, valued for their superior anti-loosening performance. |
| Mechanical | Widely used in mechanical, electronic, automotive, and construction sectors for connecting various components, circuit boards, engines, and building structures. |
| Energy | Critical for connecting power generation equipment and transmission lines in the energy industry. |
| Architectural | Used in construction engineering, shipbuilding, and petrochemical industries to enhance structural integrity and equipment stability. |
