Supplier's note

  1. Technical Breakthroughs:

    • Star-shaped teeth: Reduces rotational slippage by 40% compared to flat washers.
    • Black oxide coating: Offers 2x longer corrosion resistance than uncoated steel.
    • Spring steel material: Withstands 30% higher cyclic stress than conventional washers.

  2. Version Selection Guide:

    • Base Model: Suitable for standard automotive or light industrial use (e.g., securing car engine components).
    • Advanced Model: Ideal for heavy machinery or outdoor equipment where prolonged exposure to moisture is expected.
    • Pro Model: Designed for extreme environments (e.g., aerospace or offshore platforms) requiring high-temperature stability and ultra-corrosion resistance.

With the Pro Model’s 1,560 N load capacity, you can safely secure heavy-duty machinery joints that endure frequent vibrations. The Premium coating ensures durability in marine or chemical processing settings.
