Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • High-Performance Fastening: Designed for secure and durable fastening in industrial, automotive, and construction applications, featuring corrosion-resistant stainless steel and hexagonal heads for easy installation with standard tools.
  • Customizable Specifications: Supports tailored thread sizes (M3–M20), lengths (e.g., 20mm), and materials (stainless steel, carbon steel, alloy steel, etc.) to meet specialized engineering or assembly requirements.

Key features

  • 1. Material Technology

    • With corrosion-resistant stainless steel construction, ensure durability in harsh environments compared to traditional carbon steel fasteners*.

  • 2. Interactive Design

    • With hexagonal head design, easily fasten and tighten components using standard wrenches or sockets for seamless assembly and disassembly.

  • 3. Performance Parameters

    • With customizable thread sizes (M3 to M20) and lengths, accommodate diverse project requirements across industrial, automotive, and construction applications*.

  • 4. Scenario Solutions

    • Designed for industrial and outdoor environments, withstand prolonged exposure to moisture, chemicals, and extreme temperatures due to stainless steel’s inherent resilience.

  • 5. Certification Standards

    • Certified to global standards like DIN 931 and ASME, ensuring compliance with engineering specifications for reliability in critical applications.

  • Notes:

    • The "interactive design" highlights tool compatibility, aligning with the hexagonal head’s practicality.

Supplier's note

  1. Three Technical Breakthroughs:

    • Stainless Steel A4 Grade: Triple the corrosion resistance of standard steel, enabling use in chemical plants.
    • Precision Thread Tolerance (DIN 933): 20% tighter fit than DIN 931, reducing vibration loosening.
    • Customizable Thread Profiles: Adapt to non-standard machinery designs (e.g., aerospace components).

  2. Version Selection Guide:

    • Base Model: Ideal for standard industrial assembly (e.g., HVAC systems) where cost-efficiency is prioritized.
    • Advanced Model: Suitable for automotive or outdoor equipment needing enhanced durability (e.g., farm machinery).
    • Pro Model: Best for extreme environments (e.g., offshore platforms) requiring high-temperature and corrosion resistance.

*IP ratings indicate corrosion protection levels per international standards.
