Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Component Fixation: The Spring Steel U-nut Assembly is designed to fasten bolts and screws without requiring additional washers or nuts, offering a streamlined solution for securing components in place.
  • Corrosion Resistance: Galvanized and coated finishes (e.g., zinc-flake, black oxide) ensure durability in moisture-rich or chemically exposed environments, extending product longevity.

Key features

  • 1. Corrosion-Resistant Material Technology

  • With a galvanized or coated finish (e.g., zinc-flake, black oxide), these U-nuts resist corrosion in harsh environments like automotive or industrial settings. ~30% longer lifespan than uncoated fasteners* [*Disclaimer: Based on internal testing; actual results may vary].

  • 2. Simplified Installation Design

  • With a U-shaped spring steel body, you can secure components without additional washers or nuts, streamlining assembly and reducing part inventory costs.

  • 3. Versatile Thread Compatibility

  • With thread sizes ranging from M4 to M10, these U-nuts adapt to diverse bolt requirements, offering ~50% more adaptability than single-size fasteners*.

  • 4. High-Performance Scenario Solutions

  • Designed for automotive and industrial applications, the spring steel ensures secure clamping in high-vibration environments, enabling ~40% faster assembly line setup times* compared to traditional fasteners.

  • 5. Eco-Friendly Certification Standards

  • RoHS certification ensures compliance with environmental regulations, making these fasteners ideal for industries prioritizing sustainable materials and manufacturing practices.

Supplier's note

  1. Three Technical Breakthroughs:

    • Galvanized Finish: Triple the corrosion resistance of uncoated steel, enabling safe use in marine or chemical environments.
    • Custom Thread Sizes: With M4–M18 options, users can optimize torque strength for precise applications.
    • RoHS Compliance: Ensures global adoption without compromising on material performance.
  2. Optimal Version Selection:

    • Base Model: Ideal for standard automotive assembly lines or indoor machinery.
    • Advanced Model: For moderate chemical exposure (e.g., food processing) or outdoor equipment.
    • Pro Model: Required for extreme environments (e.g., offshore drilling) where high load capacity and temperature stability are critical.

With the Pro Model’s zinc-flake coating, you can secure components in saltwater environments without rust. Pair its HRC 55 steel with M10 threads to handle heavy-duty machinery vibrations.
