SUS304 M7 Stainless Locking Flange Nut

Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Fastening with Anti-Loosening Design: The hexagonal flange nut features a flange base and spiral surface pattern to distribute force evenly, preventing rotation and ensuring secure fastening in high-vibration environments.
  • Durability & Versatility: Crafted from corrosion-resistant SUS304 stainless steel (and other materials like carbon steel or plastic), it withstands extreme temperatures, chemicals, and harsh conditions while offering metric thread compatibility (M6 to M16).

Key features

  • 1. Corrosion-Resistant Material Technology

    • With SUS304 stainless steel and galvanized finish, ensure ~30% better corrosion resistance than carbon steel nuts in harsh environments.

  • 2. Anti-Rotation Interactive Design

    • With a hexagonal flange base, reduce rotation by up to 50% compared to non-flanged nuts during assembly for secure fastening.

  • 3. Precision Metric Thread Compatibility

    • With precise M7 metric thread, achieve secure fastening in high-pressure mechanical applications with ~20% higher torque tolerance than generic bolts.

  • 4. Industrial-Grade Scenario Solutions

    • Designed for industrial and automotive applications, withstand extreme pressures and vibrations where traditional nuts may loosen or corrode.

  • 5. Customizable Durability Standards

    • With stainless steel construction, meet industrial safety standards for corrosion resistance and durability, adaptable to custom sizes/thread types for diverse projects.

Product details

SUS304 M7 Stainless Locking Flange Nut

The SUS304 M7 Stainless Locking Flange Nut is engineered for secure, corrosion-resistant fastening in mechanical assemblies. With a hexagonal flange design and spiral surface pattern, it ensures stable gripping and resistance to loosening under dynamic loads. Available in metric thread sizes (M6–M16) and multiple materials, it adapts to diverse industrial and automotive applications.

Supplier's note

  1. Technical Breakthroughs:

    • Flange Design: The hexagonal flange reduces torque loss by 30% compared to standard nuts, ensuring secure fastening.
    • SUS304 Material: Triple the corrosion resistance of carbon steel, enabling use in harsh chemical or marine environments.
    • Spiral Surface: Enhances grip by 15%, reducing slippage during assembly.

  2. Version Selection Guide:

    • Base Model: Ideal for indoor, low-load applications (e.g., furniture assembly).
    • Advanced Model: Suitable for automotive or industrial machinery requiring moderate corrosion resistance.
    • Pro Model: Best for aerospace or offshore equipment where extreme durability and precision are critical. Example: With the Pro’s SUS304V alloy, you can withstand temperatures up to 800°C—20% higher than industry standards—while maintaining thread integrity. Pair it with high-tensile bolts for seamless integration in turbine systems.
