Supplier's note

  1. Three Breakthrough Features:

    • Flange Head Design: Reduces stress concentration by 40% compared to flat heads.
    • Zinc Plating: Offers 20% better corrosion resistance than uncoated steel.
    • M7 Thread Compatibility: Ensures seamless integration with 95% of automotive wheel systems.

  2. Optimal Version Selection:

    • Base Model: Ideal for general automotive use (e.g., daily drivers) where cost efficiency is prioritized.
    • Advanced Model: Preferred by racing teams and industrial users needing corrosion resistance in harsh environments.
    • Pro Model: Tailored for high-end applications like marine equipment or luxury vehicles, where both strength and aesthetics matter.

With the Pro Model’s 650 MPa strength, you can secure heavy-duty machinery joints that withstand 30% more force than standard bolts. Pair its copper plating with flange heads to ensure zero slippage in vibrating engine compartments.
