Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Class 10.9 steel hex head screws deliver exceptional reliability in machinery assembly, structural steel connections, and automotive components. The zinc yellow-chromate plating provides superior corrosion protection where chemical exposure or outdoor conditions threaten fastener integrity. With M8 coarse threading (1.25mm pitch) and partial threading design, these screws maintain optimal clamp load distribution while resisting loosening under dynamic loads. The external hex drive ensures maximum torque application during installation, making them ideal for high-vibration environments where metric fasteners must maintain precise tension over extended service periods.
Specification Summary & Compliance
This M8 x 1.25 x 50mm hex head screw features Class 6h thread fit tolerance and 22mm minimum thread length according to ISO 4014 (DIN 931) manufacturing specifications. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring unrestricted use in international industrial markets while maintaining the mechanical properties required for Class 10.9 strength grade applications.
