Key Features & Benefits at a Glance

  • Enhanced load distribution with a 22mm flange diameter, reducing surface pressure and preventing damage to connected materials.
  • Superior corrosion resistance thanks to the black-oxide steel coating, extending service life in harsh industrial environments.
  • Reliable thread engagement with Class 6G fit and coarse 1.5mm pitch, ensuring secure fastening and vibration resistance.
  • Easy installation and removal using standard 17mm external hex drive, compatible with common tools for efficient maintenance.
  • Compliance with environmental standards including REACH and RoHS 3, making it safe for regulated industries.
  • Durable construction from steel material, providing high tensile strength for heavy-duty applications.
  • Cost-effective performance by combining flange design with metric threading, eliminating the need for separate washers.

Professional Applications & Engineering Value

This M10 flange nut is engineered to address common industrial challenges such as loosening under vibration and corrosion in demanding settings. Made from black-oxide steel, it offers a protective layer that resists rust and wear, ideal for automotive, machinery, and construction applications. The flange design distributes clamping force evenly, reducing the risk of material fatigue, while the Class 6G thread fit and coarse 1.5mm pitch ensure quick assembly and robust performance in high-stress environments. Its metric threading and external hex drive simplify integration with standard components, enhancing operational efficiency and reliability in B2B procurement scenarios.

Specification Summary & Compliance

This flange nut adheres to precise dimensional standards, including a Class 6G thread fit per metric specifications, with a thread size of M10 and pitch of 1.5mm. It meets manufacturing guidelines for consistent performance and is compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring environmental safety and suitability for global industrial use.
