Supplier's note

  1. Key Technical Breakthroughs:

    • Knurled Surface: Enhances grip by 40% compared to smooth inserts, preventing slippage in dynamic applications.
    • Material Versatility: Brass enables conductivity for EMI shielding, while stainless steel exceeds industry corrosion standards by 50%.
    • Custom Thread Sizes: M2 to M8 compatibility covers 90% of industrial fastening needs.

  2. Version Selection Guide:

    • Base Model: Ideal for general assembly in non-corrosive environments (e.g., office equipment).
    • Advanced Model: Preferred for marine or chemical processing where +15% corrosion resistance and higher temperature tolerance (up to 150°C) are critical.
    • Pro Model: Best for high-stress aerospace or electronics applications, where tripled corrosion resistance and superior conductivity enable safe handling of sensitive components.
