Product Parameter (Specification)

Product Feature

1- High precision and stability

Our Pre-applied Thread Locking Bolts for Automotive Applications with High dimensional tolerance and fitting accuracy ensure no leakage or shaking during the connection, rotation and sealing of the whole machine. Strong installation consistency reduces debugging time for the whole machine.

2-High corrosion resistance and long service life

Made of corrosion-resistant materials such as stainless steel, nickel-plated alloy and copper alloy. Adapt to the humid environment, acid-base cleaning solution and water mist in car wash shops. Long service life reduces replacement frequency and maintenance costs for customers.

3-High pressure resistance and excellent sealing performance

Suitable for high-pressure water pipelines, rotating mechanisms and pump assemblies. Reliable sealing prevents water leakage and improves the efficiency of the whole machine.

Application

1-Pre-applied Locking Coating

The Pre-applied Thread Locking Bolts for Automotive Applications come with a pre-coated locking patch that eliminates the need for liquid adhesives during assembly. They are ready to use straight out of the package, simplifying the installation process.

2-Excellent Vibration Resistance

Maintains consistent clamp load under continuous vibration and impact, effectively preventing loosening and ensuring long-term joint reliability.

3-Precise Torque Control

The pre-applied coating provides a consistent coefficient of friction, enabling accurate and repeatable torque application—critical for automotive assembly standards.

4-Sealing and Temperature Resistance

Offers a sealing effect to prevent fluid leakage while withstanding high temperatures and chemical exposure commonly found in engine compartments and underbody applications.

5-Consistent Quality

Precision-controlled coating thickness and placement eliminate variability from manual adhesive application, making these bolts ideal for high-volume automated assembly lines.

Production Details

Manufactured by Qimao metal manufacturer, these Pre-applied Thread Locking Bolts for Automotive Applications are crafted from high-strength C1022 carbon steel, heat-treated via carburizing and quenching for enhanced durability. The surface features a black oxide finish to resist corrosion, while the threads are pre-coated with a blue nylon patch to deliver reliable anti-loosening performance under automotive vibration, ensuring secure assembly and long-term stability.
