Professional Applications & Engineering Value
This M20 hex head screw delivers critical engineering solutions where high tensile strength and corrosion resistance are paramount. The Class 8.8 steel construction combined with zinc plating addresses common failure points in heavy machinery, structural frameworks, and outdoor equipment by preventing thread stripping and environmental degradation. Its extra fine metric thread (1.5mm pitch) provides superior clamping force in thin materials and vibration-prone assemblies, while the fully threaded design ensures uniform stress distribution. Ideal for industrial applications requiring precise external hex drive installation, this fastener maintains integrity under sustained loads, reducing maintenance cycles and improving operational safety.
Specification Summary & Compliance
Manufactured to exact ISO 8676/DIN 961 specifications with Class 6h thread fit for precision alignment. The screw meets Rockwell C21 hardness standards and maintains dimensional consistency across the 60mm length. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to international safety and environmental protocols for industrial components.
