Professional Applications & Engineering Value
These M12 hex head screws with Class 10.9 strength rating are engineered to solve critical fastening challenges in heavy machinery, structural steelwork, and industrial equipment assembly. The metric coarse thread (1.75mm pitch) combined with steel construction provides superior vibration resistance, preventing loosening in dynamic applications. The blue-dyed zinc-plated finish offers both corrosion protection and visual identification benefits in complex assemblies. With external hex drive design, these fasteners deliver optimal torque transfer during installation, reducing the risk of stripping and ensuring consistent clamping force. The fully threaded configuration maximizes engagement in thick materials, making them ideal for construction, automotive, and manufacturing applications where reliability is paramount.
Specification Summary & Compliance
This metric hex head screw features M12 x 1.75mm coarse threading with Class 6g thread fit tolerance for precision engagement. Manufactured to ISO 4017 specifications (equivalent to DIN 933) with 35mm length, 19mm head width, and 7.5mm head height dimensions. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors while meeting international quality standards for heavy-duty applications.
