Our M12 hexagon nuts with flange are designed for efficient and reliable assembly:
- Standard Hexagon Shape: The familiar hexagon shape allows for easy tightening and loosening with standard wrenches and sockets, common tools in automotive workshops and assembly lines.
- Integrated Flange: The pre-attached flange simplifies the assembly process, reducing the number of parts and ensuring proper load distribution.
- Consistent Torque Application: The flange provides a stable bearing surface for applying torque, leading to more consistent and accurate clamping force.
Key Advantages for Your Applications:
- Enhanced Vibration Resistance: The wider bearing surface of the flange significantly improves resistance to loosening under the dynamic conditions of automotive use.
- Improved Load Distribution: The flange spreads the clamping force, reducing stress on connected parts and preventing damage.
- Simplified Assembly Process: Eliminating the need for separate washers reduces part count and assembly time, boosting efficiency.
- Secure and Reliable Fastening: Ensures strong and durable connections crucial for automotive safety and performance.
- Compliance with Key Standards: Meets the requirements of EN 1661 (DIN 6923 / GB/T 6177.1), ensuring dimensional accuracy and material quality.
- Reduced Risk of Damage: The flange protects the mating surface from scratches and indentations during tightening.
Ideal for:
- Chassis and Suspension Systems: Securing components like shock absorbers, control arms, and stabilizer bar links where vibration resistance is paramount.
- Engine and Powertrain Mounting: Fastening engine mounts, transmission mounts, and exhaust system components, benefiting from the wider load distribution.
- Body Panel Assembly: Providing secure and efficient fastening of body panels, reducing the number of parts required.
- Steering System Components: Securing linkages and other critical steering elements where reliable fastening is essential for safety.
- Braking System Components: Fastening caliper brackets and other non-critical braking system parts.
- Interior and Exterior Trim: Providing a secure and integrated fastening solution for various trim elements.
