Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Secure Threaded Fastening: Designed as countersunk head open blind threaded inserts, these rivet nuts provide a durable and reliable solution for securing parts in blind-hole applications without requiring access to the rear side.
  • Metric Thread Compatibility: Available in sizes M4 to M12 (metric system), they accommodate a wide range of bolt/thread specifications for precise mechanical assembly.

Key features

  • 1. Galvanized Steel Construction for Enhanced Durability

    • With a galvanized steel body, you can ensure corrosion resistance and long-term reliability in harsh environments.

  • 2. Countersunk Head & Hexagonal Design for Versatile Installation

    • With a countersunk head and hexagonal shape, you can achieve flush mounting and easy tightening/loosening with standard wrenches.

  • 3. Wide Thread Size Range for Universal Compatibility

    • With thread sizes from M4 to M12, you can accommodate diverse applications requiring precise fitment.

  • 4. Open Blind Threaded Insert for Blind Hole Applications

    • With an open blind design, you can install in confined spaces without rear access, ideal for automotive and construction projects.

  • 5. Metric System Compliance for Global Use

    • With metric thread standards (ISO), you can ensure seamless compatibility with international hardware systems.

Product details

M4 M5 M6 M8 M10 M12 Steel Rivnut Countersunk Head Open Blind Threaded Insert Full Hex Rivet Nut

The M4-M12 Steel Rivnut Countersunk Head Open Blind Threaded Insert Full Hex Rivet Nut is a versatile fastening solution designed for secure, blind-side fastening in metal assemblies. With a galvanized finish and metric thread sizes (M4 to M12), these nuts ensure corrosion resistance and precision fitment across automotive, industrial, and mechanical applications.

Supplier's note

  1. Three Breakthroughs:

    • Galvanized Finish: Provides 30% longer lifespan in marine or industrial settings compared to uncoated steel.
    • Metric Thread Precision: Ensures 99.9% compatibility with global bolt standards.
    • Countersunk Design: Reduces surface protrusion by 50%, enabling seamless integration.

  2. Optimal Version Selection:

    • Base Model: Ideal for standard automotive or light industrial use where cost efficiency is prioritized.
    • Advanced Model: Recommended for machinery in corrosive environments (e.g., food processing) due to enhanced coating.
    • Pro Model: Suitable for aerospace or extreme-temperature applications, with a temperature range exceeding industry benchmarks by 50%.
