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

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.

Material Specifications

Aluminum	Offers excellent thermal and electrical conductivity but requires careful machining due to its soft nature.
Titanium	Requires EDM machining with deionized water to control heat during processing of this viscous alloy.
Steel	Strong material often machined with wire cutting machines for complex features, requiring heat management.
Brass	High 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
