Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Attachments: Stainless steel and carbon steel U-bolts, wire rope clips, and tie-downs provide reliable fastening for pipes, cables, and structural components.
  • Versatile Fastening Solutions: Includes lag screws, nuts, bolts, and customizable configurations to meet diverse assembly and anchoring needs across materials like wood, metal, and wire ropes.

Key features

  • 1. Corrosion-Resistant Materials

    • With stainless steel and carbon steel options, ensure durability in harsh environments such as industrial and marine applications. Stainless steel variants offer ~30% higher corrosion resistance compared to plain iron fasteners*.

  • 2. Enhanced Surface Treatments

    • With white zinc and hot-dip galvanizing (HDG) coatings, reduce rust and extend lifespan in outdoor or humid conditions. HDG-treated bolts show ~25% longer service life than untreated steel in corrosive settings*.

  • 3. Versatile Dimensional Compatibility

    • With lengths ranging from 20mm to 80mm and thread sizes from M2 to M36, accommodate diverse fastening needs for automotive, construction, and machinery assembly. Outperforms standard bolts limited to 1-2 thread sizes*.

  • 4. Multi-Scenario Application Design

    • Designed for industrial, automotive, and construction uses, these U-bolts and tie-downs securely fasten pipes, cables, and heavy equipment. Their adjustable U-shape and reinforced nuts/bolts enable ~40% stronger clamping force than generic fasteners*.

  • 5. Global Compliance Standards

    • Compliant with ANSI, DIN, ISO, and other international standards, ensuring compatibility with global engineering specifications. Meets or exceeds safety requirements for commercial and industrial-grade applications.

Supplier's note

  1. Technical Breakthroughs:

    • Material Diversity: Stainless steel variants offer triple the corrosion resistance of carbon steel.
    • Surface Treatment: HDG coating in Pro models provides 50% better rust protection than zinc.
    • Global Compliance: JIS/DIN/ISO certifications ensure seamless integration into international supply chains.

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial or automotive applications where cost is prioritized.
    • Advanced Model: Suitable for marine or chemical environments requiring moderate corrosion resistance.
    • Pro Model: Best for heavy-duty outdoor infrastructure or offshore projects demanding extreme durability.

With the Pro model’s HDG coating, you can ensure secure fastening in saltwater environments. Pair its high load capacity with stainless steel threads for long-term structural integrity.
