Heavy-Duty Wheel Hub Bolts M14×1.5 Zinc Electroplated/Black Oxide, ISO 7412 Classes 8.8 and 10.9

——

These wheel hub bolts are specifically designed to withstand the significant shear forces, tensile stresses, and vibrations encountered in wheel assemblies. The M14 thread diameter and 1.5mm thread pitch are common specifications for many heavy-duty applications, ensuring a strong and reliable connection between the wheel hub and the wheel. The availability in ISO 7412 Classes 8.8 and 10.9 allows you to select the optimal strength grade for your specific load requirements.

Designed for Ease of Use:

Our Heavy-Duty Wheel Hub Bolts M14×1.5 are designed for straightforward and secure installation:

  • Standard M14×1.5 Thread: This widely used thread specification ensures compatibility with a broad range of wheel hubs and wheels.
  • Hex Head Design: The robust hex head provides a secure grip for standard wrenches and sockets, facilitating efficient tightening to the specified torque.
  • Durable Surface Finishes: The Zinc Electroplated finish offers good corrosion resistance for general applications, while the Black Oxide finish provides a cost-effective alternative with moderate corrosion protection and a distinct appearance.
  • ISO 7412 Compliance: Adherence to the ISO 7412 standard ensures dimensional accuracy and consistent mechanical properties.

Key Advantages for Your Applications:

  • High Strength (Classes 8.8 & 10.9): Provides exceptional resistance to shear forces and tensile loads, ensuring secure wheel attachment under heavy loads and demanding conditions.
  • Standard M14×1.5 Thread: Ensures broad compatibility with various wheel hubs and wheels used in heavy-duty applications.
  • Reliable ISO 7412 Compliance: Guarantees dimensional accuracy and consistent mechanical properties for dependable performance.
