Professional Applications & Engineering Value

These M16 hex head screws deliver critical performance where structural integrity matters most. The Class 10.9 steel construction provides exceptional resistance to elongation and shear forces, making them ideal for heavy machinery, structural steel connections, and industrial equipment assembly. The partially threaded design allows for precise clamp load distribution while the coarse metric thread ensures rapid installation in tough materials. With blue-dyed zinc plating creating an additional barrier against oxidation, these fasteners maintain their integrity in outdoor or corrosive environments. Engineers specify these ISO 4014 compliant hex screws for applications requiring predictable failure points and consistent torque-tension relationships, from construction projects to manufacturing equipment where vibration resistance is paramount.

Specification Summary & Compliance

This 70mm length hex head screw features M16x2mm coarse threading with Class 6g thread fit per ISO metric standards, ensuring precise dimensional accuracy. Manufacturing follows ISO 4014 specifications (equivalent to DIN 931) for hex head bolts, guaranteeing consistent quality and interchangeability. The fastener meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations for chemical safety. With 38mm minimum thread length and right-hand thread direction, these screws provide reliable performance across industrial applications requiring high-strength metric fasteners.
