Professional Applications & Engineering Value
This M16 hex head screw delivers critical engineering solutions where high tensile strength and corrosion resistance are paramount. The zinc plated steel construction prevents oxidation in manufacturing facilities, automotive assemblies, and structural frameworks exposed to moisture. With its fine 1.5mm pitch and Class 6h thread fit, the fastener maintains clamping force under vibration, eliminating the need for frequent retightening in machinery and equipment. The fully threaded design ensures uniform stress distribution across the entire 50mm length, while the external hex drive enables high-torque installation without stripping. Engineered to ISO 8676 DIN 961 specifications, this Class 8.8 metric screw provides reliable performance in heavy-duty industrial applications where fastener failure is not an option.
Specification Summary & Compliance
Manufactured to precise metric dimensions with M16 x 1.5mm fine thread spacing and Class 6h thread fit tolerance. The steel fastener meets ISO 8676 DIN 961 manufacturing standards with Class 8.8 strength grade certification. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for restricted substances. Features right-hand thread direction and fully threaded construction along the 50mm length with 24mm hex head width and 10mm head height.
