• Full regulatory compliance meeting international ISO 4014/DIN 931 standards plus RoHS 3 and REACH environmental directives

Professional Applications & Engineering Value

This M12 hex head screw delivers critical engineering solutions where high tensile strength and reliable fastening are paramount. The Class 10.9 steel construction provides exceptional resistance to vibration loosening and mechanical stress, making it ideal for heavy machinery, structural steel connections, and industrial equipment assembly. The partially threaded design with 30mm minimum thread length allows for precise clamp load distribution while the unthreaded shank section resists shear forces. With metric coarse threading (1.75mm pitch) and external hex drive, installation efficiency is maximized in construction, manufacturing, and automotive applications where speed and reliability are essential. The combination of right-hand threading and standardized dimensions ensures compatibility with existing industrial components and tooling systems.

Specification Summary & Compliance

This fastener maintains Class 6g thread fit tolerance according to metric standards, ensuring precise mechanical compatibility. Manufacturing conforms to ISO 4014 and DIN 931 specifications for dimensional accuracy and performance consistency. The product is fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, making it suitable for global industrial supply chains and environmentally conscious manufacturing operations.
