Supplier's note

  1. Technical Breakthroughs:

    • The Pro Model’s passivated stainless steel achieves triple the corrosion resistance of industry-standard carbon steel, ideal for chemical plants.
    • Advanced Model’s hot-dip galvanized surface provides 20% thicker coating than black oxide, extending lifespan in coastal environments.
    • Thread sizes (M4–M12) are ISO-certified, ensuring universal compatibility with global machinery standards.

  2. Optimal Version Selection:

    • Base Model: Suitable for general workshops requiring basic corrosion protection (e.g., automotive assembly lines).
    • Advanced Model: Recommended for outdoor infrastructure projects where -30°C to 150°C temperature fluctuations are common.
    • Pro Model: Perfect for harsh industrial settings (e.g., oil refineries) where chemical exposure demands extreme durability.

With the Pro Model’s passivated stainless steel, you can safely fasten components in acidic environments. The Advanced Model’s enhanced coating ensures longevity in saltwater exposure. Choose the Base Model for cost-effective solutions where extreme conditions are absent.

*Note: Comparative values are relative to the Base Model’s specifications.
