S-90447A530 M10 x 215 mm DIN 931 High-Strength Metric Class 10.9 Steel Hex Head Screws

Key Features & Benefits at a Glance

• Exceptional load-bearing capability with Class 10.9 strength rating and 150,000 psi tensile strength for reliable performance in high-stress applications
• Superior wear resistance thanks to Rockwell C32 hardness, ensuring extended service life in demanding industrial environments
• Optimized thread engagement with Class 6g thread fit and coarse 1.5 mm pitch for faster installation and reduced cross-threading risks
• Secure torque transmission through external hex drive and 17 mm head width, providing excellent grip for standard wrench tools
• Versatile partial threading design with 45 mm minimum thread length, allowing both secure fastening and alignment flexibility
• Corrosion-resistant black finish on steel construction, enhancing durability while maintaining cost-effectiveness
• Global compliance assurance meeting DIN 931 specifications and environmental regulations including RoHS 3 and REACH

Professional Applications & Engineering Value

This M10 hex head screw delivers critical engineering solutions for heavy machinery, structural assemblies, and industrial equipment where high tensile strength and vibration resistance are paramount. The Class 10.9 steel construction combined with Rockwell C32 hardness prevents stripping and deformation under extreme loads, while the coarse metric thread (1.5 mm pitch) ensures rapid assembly in production environments. The partially threaded design provides unthreaded shank sections for precise component alignment, making it ideal for construction, automotive, and manufacturing applications requiring both clamping force and shear resistance. With DIN 931 compliance and external hex drive, this fastener integrates seamlessly into European engineering specifications and standard tooling systems.

Specification Summary & Compliance

This metric hex head screw features precise Class 6g thread fit tolerance according to ISO standards, ensuring consistent engagement across mating components. Manufacturing conforms to DIN 931 specifications for dimensional accuracy, including 17 mm head width and 6.4 mm head height. The product maintains full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for global industrial supply chains without hazardous substance restrictions.
