Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Performance Fastening: Stainless steel hex nuts with Grade 12.9/10.9 strength ratings provide exceptional tensile and shear load resistance, ideal for heavy-duty mechanical and industrial applications.
  • Versatile Design: Hexagonal shape ensures secure gripping with wrenches/socket wrenches, enabling precise torque control in assembly and repair tasks.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With a stainless steel body and finishes like nickel-plated or polished surfaces, you can ensure long-lasting durability in harsh environments. These nuts are ~20% more corrosion-resistant than uncoated steel alternatives*.

  • 2. High-Performance Tensile Strength

    • With Grade 12.9/10.9 steel, you can achieve up to 15% higher load-bearing capacity than Grade 8.8 nuts*, making them ideal for heavy-duty applications like automotive and industrial machinery.

  • 3. Universal Hexagonal Design

    • With a hexagonal shape and precise threading (M2 to M21), you can easily tighten or loosen nuts with standard wrenches, outperforming slotted nuts in torque control precision*.

  • 4. Versatile Metric/Imperial Compatibility

    • With thread sizes spanning metric (e.g., M18, M20) and imperial systems, you can adapt to both domestic and global projects, offering ~30% more size options than standard nut ranges*.

  • 5. RoHS Compliance for Global Use

    • With RoHS certification, you can meet strict environmental and safety regulations, unlike non-compliant products that risk legal or supply chain issues*.

  • Notes:

    • Material Technology: Highlights corrosion resistance and premium finishes.

Supplier's note

  1. Technical Breakthroughs:

    • Grade 12.9 Steel: 30% higher tensile strength than Grade 10.9, enabling use in aerospace and high-stress machinery.
    • Zinc-Flake Coating: 50% thicker corrosion protection than standard galvanization.
    • Precision Thread Tolerance (2h): Ensures seamless mating with bolts, reducing assembly errors.

  2. Optimal Version Selection:

    • Base Model: Ideal for general industrial use (e.g., furniture assembly) where cost efficiency is prioritized.
    • Advanced Model: Suited for automotive and construction applications requiring extreme load-bearing capacity.
    • Pro Model: Tailored for specialized sectors like marine engineering, with customizable coatings and grades for corrosive or high-temperature environments.

With the Pro’s triple-layer PTFE coating, you can ensure longevity in chemical plants. Pair its 1220 MPa strength with black oxide finish for low-friction, high-stress applications. For hobbyists or small-scale projects, the Base Model offers reliable performance at a lower cost.
