• Corrosion-resistant black finish offering improved durability and professional appearance in various operating conditions

Professional Applications & Engineering Value

This M10 hex head screw delivers critical engineering solutions where vibration resistance and structural integrity are paramount. The Class 10.9 steel construction provides exceptional fatigue resistance, making it ideal for heavy machinery, automotive assemblies, and structural frameworks subjected to dynamic loads. The partially threaded design allows the unthreaded shank to act as a precision pilot, preventing cross-threading while maintaining clamp load in bolted joints. With coarse metric threading and external hex drive, installation becomes significantly faster in production environments, reducing assembly time while ensuring consistent torque application. The combination of high tensile strength and Rockwell C32 hardness addresses common failure points in industrial equipment, providing reliable performance in manufacturing, construction, and mechanical engineering applications where fastener failure is not an option.

Specification Summary & Compliance

This metric hex head screw features precise M10x1.5 coarse threading with Class 6g tolerance for consistent fitment. Manufacturing follows DIN 931 specifications for dimensional accuracy and quality control. The fastener maintains compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and material safety. With a defined thread length of 45mm minimum and total length of 205mm, the screw provides standardized dimensions for engineering calculations and replacement purposes across industrial applications.
