Supplier's note

  1. Technical Breakthroughs:

    • N52 Grade: Industry-leading strength (52 MT) enables secure handling of heavy loads.
    • Multi-Coating Options: Five coatings (e.g., epoxy for chemical resistance, NiCuNi for marine use) expand application versatility.
    • Precision Tolerances: ±0.5% in Pro models ensures flawless integration into precision machinery.

  2. Version Selection Guide:

    • Base Model (N35): Ideal for light industrial tasks (e.g., securing small parts in assembly lines).
    • Advanced Model (N42): Suitable for moderate loads (e.g., clamping tools in workshops).
    • Pro Model (N52): Perfect for heavy-duty applications (e.g., stabilizing large machinery or lifting scrap metal). With its triple-certified NiCuNi coating, the Pro model withstands extreme environments while maintaining structural integrity.
