GB 6176 hex nuts, automotive nuts, large stock, equivalent size DIN 971, ISO 8673

Our GB 6176 Hexagon Nuts, Style 2 - Fine Pitch Thread, are engineered for efficient and reliable integration into automotive assembly processes:

• Standard Hexagon Shape: The familiar hexagonal profile ensures seamless compatibility with standard automotive wrenches and sockets, facilitating quick and efficient tightening and loosening during assembly and maintenance.

• Fine Pitch Threading: While requiring more turns than coarse threads, the fine pitch allows for smoother and more controlled engagement with the bolt threads, aiding in achieving precise torque application.

• Chamfered Nut Face: Typically features a chamfer on the bearing face to facilitate easy starting and engagement with the bolt.

Key Advantages for Your Applications:

The unique combination of Style 2 construction and fine pitch threading provides significant benefits crucial for automotive reliability and performance:

• Superior Strength (Style 2): Style 2 nuts are thicker than Style 1 nuts, offering a larger load-bearing surface on the threads and increased axial strength. This makes them ideal for use with high-strength bolts in applications subjected to significant tensile loads.

• Exceptional Vibration Resistance (Fine Pitch): The smaller helix angle of the fine pitch thread provides a greater self-locking effect compared to coarse threads, making GB 6176 nuts highly resistant to loosening caused by the dynamic loads and vibrations prevalent in automotive environments.

• Precise Preload Control (Fine Pitch): Fine threads allow for finer adjustment of the clamping force (preload) during tightening. This is critical for ensuring optimal joint integrity in sensitive components and preventing over-tightening that could cause damage.

• Enhanced Fatigue Resistance: The larger minor diameter of fine pitch threads (compared to coarse) can contribute to improved fatigue resistance in bolted joints under cyclic loading, a common challenge in vehicles.

• Reliable Performance: Manufactured to the stringent requirements of the GB 6176 standard, these nuts offer consistent dimensions, material properties, and reliable performance you can trust.

• Global Standard Equivalence: GB 6176 is often considered equivalent to international standards like ISO 8674 and DIN EN ISO 8674, facilitating ease of global sourcing and ensuring interchangeability in many applications worldwide.

Ideal for:

GB 6176 Hexagon Nuts, Style 2 - Fine Pitch Thread, are ideally suited for demanding automotive applications where strength, vibration resistance, and precise clamping are essential:

• Chassis and Suspension Systems: Securing high-stress connections in the vehicle frame, suspension arms, and mounting points where high loads and vibrations are present.

• Powertrain Assemblies: Fastening engine blocks, transmission housings, and drivetrain components where reliable, high-strength, and vibration-resistant joints are critical for performance and durability.

• Braking Systems: Used in certain areas of braking systems where precise torque application and resistance to loosening are vital for safety.

• Steering Mechanisms: Providing secure and reliable connections in steering linkages subjected to dynamic forces.

• Heavy-Duty Vehicle Construction: Essential for structural connections in trucks, buses, and other commercial or off-highway vehicles.

• Applications Requiring Precise Preload: Any assembly where controlled clamping force is necessary for optimal function or to prevent damage to components.
