Professional Applications & Engineering Value
These M12 hex head screws deliver exceptional engineering value in heavy-duty applications where vibration resistance and structural integrity are critical. The Class 10.9 steel construction with Rockwell C32 hardness ensures they withstand extreme mechanical stresses in machinery assembly, structural steel connections, and automotive components. The blue-dyed zinc plating not only provides corrosion protection but also facilitates quality control in multi-fastener assemblies. With coarse metric threading and partial threading, these screws offer superior grip in both metallic and non-metallic materials, preventing stripping and maintaining clamp load in dynamic environments. Their ISO 4014 compliance ensures seamless integration into global manufacturing processes and replacement part systems.
Specification Summary & Compliance
This hex head screw features M12 x 1.75mm coarse threading with Class 6g thread fit tolerance and 80mm length (30mm minimum thread length). Manufactured to ISO 4014 specifications (equivalent to DIN 931) with external hex drive. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
