Supplier's note

  1. Technical Breakthroughs:

    • Stainless Steel 316 (Pro Model): Triple the corrosion resistance of industry benchmarks, enabling safe use in marine or chemical environments.
    • Reinforced Nylon Caps (Advanced/Pro): 20% higher load capacity than standard plastic caps, ensuring durability in heavy-duty applications.
    • Metric Thread Compatibility: Universal fitment across global standards, reducing inventory complexity.

  2. Version Selection Guide:

    • Base Model: Ideal for basic indoor applications (e.g., furniture assembly) where cost-efficiency is prioritized.
    • Advanced Model: Perfect for industrial or outdoor use (e.g., machinery, garden structures) requiring color differentiation and moderate load handling.
    • Pro Model: Tailored for extreme environments (e.g., offshore equipment, chemical plants) where corrosion resistance and high-strength performance are critical.

With the Pro model’s 316 stainless steel, you can ensure longevity in corrosive settings. The Advanced model’s 3-color options simplify organization in maintenance-heavy workflows. Choose the Base model for straightforward, budget-friendly solutions.
