Key Features & Benefits at a Glance

  • Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments.
  • Enhanced load distribution from the integrated flange design, reducing surface pressure and preventing material damage.
  • Secure anti-loosening performance due to serrated locking features under the head, maintaining joint integrity under vibration.
  • High mechanical strength with 100,000 psi tensile strength and Rockwell B100 hardness for demanding applications.
  • Precise and reliable fastening ensured by Class 6g thread fit and M10x1.5mm coarse thread for quick assembly.
  • Easy installation and removal with standard external hex drive, compatible with common tools.
  • Full thread engagement along the 30mm length, providing consistent clamping force across the entire fastener.

Professional Applications & Engineering Value

This M10 hex head screw is engineered to address critical fastening challenges in industrial settings. The 18-8 stainless steel material offers excellent resistance to rust and oxidation, making it suitable for outdoor, marine, or chemically exposed environments. The flanged design eliminates the need for separate washers, distributing clamp load over a wider area to prevent surface indentation and maintain structural integrity. Combined with coarse metric threading and Class 6g thread fit, it ensures rapid, accurate installation in machinery, automotive assemblies, and construction frameworks where vibration resistance and high tensile strength are paramount. The fully threaded shank and external hex drive further enhance versatility and ease of use in high-volume production lines.

Specification Summary & Compliance

This screw conforms to metric coarse thread standards with M10 diameter, 1.5mm pitch, and Class 6g thread fit for consistent dimensional accuracy. It is manufactured from 18-8 stainless steel with a flange diameter of 22.3mm and overall length of 30mm. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
