Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Vibration-Resistant Locking: Hexagonal flange design prevents loosening under high torque or vibrations, ensuring secure fastening in dynamic environments.
  • Material Durability: Constructed from corrosion-resistant stainless steel or alloy steel, suitable for harsh industrial and outdoor conditions.
  • Easy Installation: Hexagonal head allows for quick tightening/loosening with standard tools, optimizing efficiency in manual or automated setups.

Key features

  • 1. Corrosion-Resistant Materials & Advanced Surface Treatments

    • With corrosion-resistant stainless steel and customizable surface finishes (e.g., black oxide, zinc-flake coating, or cadmium plating), these flange nuts ensure durability in harsh environments. The black coating enhances resistance to corrosion and wear while reducing glare in industrial settings.

  • 2. Hexagonal Flange Design for Secure Locking

    • With a hexagonal flange design, you can easily tighten/loosen the nut using standard tools while preventing loosening caused by vibrations or high torque. The flange provides a stable base, ideal for machinery and equipment where component security is critical.

  • 3. Versatile Size & Thread Compatibility

    • With metric and imperial thread options spanning sizes M5 to M160, these nuts accommodate diverse hardware specifications, from small mechanical parts to large industrial components. The extensive range ensures compatibility with most global standards.

  • 4. Industrial-Grade Stability & Performance

    • Designed for heavy-duty applications, these flange lock nuts maintain structural integrity under continuous torque and vibrations, making them ideal for commercial machinery, automotive systems, and industrial equipment assembly.

  • 5. Compliance with ENISO 6507 Standards

    • Certified to ENISO 6507, these nuts meet rigorous international quality and safety benchmarks, ensuring reliability in critical mechanical systems where precision and durability are non-negotiable.
