• Optimized thread engagement with Class 6g fit and coarse 1.5mm pitch for faster assembly and reduced cross-threading risk
• Secure torque transmission via external hex drive and 17mm head width, preventing tool slippage during installation
• Versatile partial threading design with 26mm minimum thread length for both clamping and alignment functions
• Consistent dimensional accuracy maintained through ISO 4014 DIN 931 manufacturing standards
• Environmental compliance assurance meeting RoHS 3 and REACH regulations for global supply chain integration

Professional Applications & Engineering Value

This M10 hex head screw delivers exceptional engineering value through its Class 8.8 steel construction and metric coarse thread design. The partially threaded configuration provides dual functionality: the threaded section ensures secure fastening while the unthreaded shank maintains precise alignment in machinery assemblies and structural frameworks. With Rockwell C21 hardness and 110,000 psi tensile strength, these industrial fasteners withstand vibration, dynamic loads, and thermal cycling in automotive, construction, and heavy equipment applications. The external hex drive and black surface treatment combine for reliable installation and moderate corrosion protection, making them ideal for both indoor and protected outdoor environments where consistent performance is critical.

Specification Summary & Compliance

Manufactured to ISO 4014 DIN 931 specifications with Class 6g thread fit tolerance and M10 x 1.5mm coarse thread spacing. The fastener maintains dimensional accuracy with 110mm total length, 17mm head width, and 6.6mm head height. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage across international markets. The Class 8.8 strength grade corresponds to mechanical properties defined in international standards for reliable performance verification.
