1. **Grade and Strength** - Rated 10.9 grade, these bolts have a minimum tensile strength of 1000 MPa and yield strength of 900 MPa, ensuring they can withstand heavy loads and high - stress conditions typical in automotive systems. This high - strength rating makes them suitable for critical components where reliability is essential. 2. **Material and Coating** - Constructed from high - quality alloy steel, which is heat - treated to achieve the 10.9 - grade strength. The galvanized color zinc finish not only provides excellent corrosion resistance, protecting the bolts from rust and oxidation in various environmental conditions, but also offers an aesthetically pleasing appearance, which can be beneficial for visible automotive parts. 3. **Design Features** - **Flange Head**: The integrated flange head increases the contact area with the mating surface, distributing load more evenly and reducing the risk of surface damage. This design also enhances anti - loosening performance, minimizing the need for additional washers in many cases. - **Toothed Anti - slip**: The underside of the flange is equipped with fine - toothed patterns. These teeth bite into the surface, creating a mechanical interlock that effectively prevents the bolts from loosening due to vibrations, which are common in automotive applications. - **Fine - thread Design**: The fine - thread pitch provides a higher number of threads per unit length, resulting in a stronger clamping force and better resistance to rotational forces. It allows for more precise adjustment and tightening, ensuring a secure fit in automotive assemblies. 4. **Application - Specific Benefits** - **Automotive Compatibility**: Specifically engineered for automotive parts, these bolts are suitable for a wide range of applications, including engine mounts, suspension systems, and body - in - white assemblies. Their high - strength, anti - slip, and corrosion - resistant properties make them reliable for securing components that are subject to constant movement, vibrations, and exposure to different weather elements. 5. **Quality Assurance** - Manufactured to strict industry standards, these bolts undergo rigorous testing for strength, dimensional accuracy, and coating integrity. Tensile tests, hardness tests, and salt - spray tests (to assess corrosion resistance) are conducted to ensure they meet or exceed the requirements for automotive use, providing consistent performance and safety. 6. **Installation and Maintenance** - The flange and fine - thread design simplifies installation, as it allows for efficient torque application and secure tightening. The anti - slip toothed feature reduces the need for additional locking devices, saving installation time and costs. Their corrosion - resistant coating also minimizes maintenance requirements, as they are less likely to degrade over time, even in harsh automotive environments.
