    Product Description

    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.

    Applications
    AutomotiveEssential for high-strength applications including automotive engines, heavy-duty machinery, and bridge construction, valued for their superior anti-loosening performance.
    MechanicalWidely used in mechanical, electronic, automotive, and construction sectors for connecting various components, circuit boards, engines, and building structures.
    EnergyCritical for connecting power generation equipment and transmission lines in the energy industry.
    ArchitecturalUsed in construction engineering, shipbuilding, and petrochemical industries to enhance structural integrity and equipment stability.
    Material Specifications
    AluminumOffers excellent thermal and electrical conductivity but requires careful machining due to its soft nature.
    TitaniumRequires EDM machining with deionized water to control heat during processing of this viscous alloy.
    SteelStrong material often machined with wire cutting machines for complex features, requiring heat management.
    BrassHigh tensile strength allows for easy machining but requires slower cutting speeds due to softness.
    Key Advantages
    • Flange design provides superior locking capability compared to standard bolts
    • Thinner flange section allows slight deformation for more secure fastening
    • Integrated flange eliminates the need for separate washers in many applications
    • Critical for wheel hub safety, ensuring stable connection between wheels and vehicle
    • Available in various configurations to match different vehicle requirements
