Professional Applications & Engineering Value

This M12 hex head screw is engineered to address critical fastening challenges in heavy-duty industrial applications such as machinery assembly, structural steelwork, and construction projects. The Class 10.9 steel construction delivers high tensile strength and fatigue resistance, preventing loosening under dynamic loads and vibration. The coarse thread pitch (1.75 mm) facilitates quicker installation and provides better performance in materials prone to stripping or where debris accumulation is a concern. With partial threading, it allows for precise clamp load distribution and is ideal for applications requiring a combination of threaded and unthreaded shaft sections. Compliant with DIN 931 standards, it ensures reliable performance in metric-based engineering designs, making it a trusted component for OEMs and maintenance teams seeking durable, specification-compliant fasteners.

Specification Summary & Compliance

This fastener features a Class 6g thread fit per ISO metric standards, ensuring precise dimensional accuracy and compatibility. It is manufactured in accordance with DIN 931 specifications for hex head screws and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its suitability for use in products distributed globally. The screw's 240 mm length and 30 mm minimum thread length provide versatility for a range of industrial fastening requirements.
