Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Structural Fastening: Designed as a heavy-duty machine bolt (M30 thread size) for securing components in high-load applications.
  • Versatile Material Options: Available in stainless steel for corrosion resistance or carbon steel with surface treatments (zinc plated/black oxide) for enhanced durability in diverse environments.

Key features

  • 1. Corrosion-Resistant Material Technology

    • With corrosion-resistant stainless steel and zinc-plated/oxide finishes, ensure long-lasting durability in harsh environments. The zinc plating provides an additional ~30% corrosion protection compared to bare steel bolts*.

  • 2. Hexagonal Head Interactive Design

    • With a hexagonal head design, achieve precise torque application using standard wrenches or sockets, reducing slippage risk by ~25% versus flat-head bolts*. The uniform grip ensures secure fastening in tight spaces.

  • 3. High-Performance Thread Specifications

    • With M30 thread size and compliance to ISO 4014/A320 standards, handle heavy loads with a tensile strength up to 600 MPa*. This exceeds general industrial-grade bolt performance requirements*.

  • 4. Versatile Scenario Solutions

    • Designed for marine, construction, and chemical-industry applications, maintain structural integrity in corrosive or high-stress environments (e.g., offshore platforms, industrial machinery). Outperforms standard bolts in continuous load scenarios*.

  • 5. Certified Quality Assurance

    • Certified to ENISO 6507 and global standards (ISO/DIN/ANSI/JIS), ensuring consistent hardness, strength, and reliability across international quality benchmarks*.

Supplier's note

  1. Technical Breakthroughs:

    • The Pro model’s 3000-hour salt spray test rating (triple industry norms) enables safe use in offshore platforms.
    • Advanced stainless steel variants offer 20% higher tensile strength than traditional steel bolts, ideal for heavy machinery.
    • Multi-standard compliance (e.g., ISO 3506) reduces certification delays in global supply chains.

  2. Version Selection Guidance:

    • Base Model: Cost-effective for general construction (e.g., steel beams) where basic corrosion resistance suffices.
    • Advanced Model: Optimal for food processing or chemical plants needing hygienic, corrosion-free fasteners.
    • Pro Model: Recommended for aerospace or oil/gas infrastructure requiring extreme durability and compliance with premium standards.

With the Pro model’s 1000 MPa tensile strength, you can secure heavy machinery components under extreme loads. The Advanced model’s black oxide finish provides 20% faster installation in high-temperature environments compared to plain finishes.
