Professional Applications & Engineering Value

This Class 10.9 steel hex head screw delivers exceptional engineering value for demanding industrial applications where failure is not an option. The M8 coarse thread with 1.25mm pitch provides excellent vibration resistance while enabling rapid assembly in production environments. The zinc yellow-chromate plating creates a robust barrier against corrosion, extending service life in exposed conditions common in construction, machinery, and automotive applications. With partial threading and precise Class 6h thread fit, this fastener concentrates strength where needed most, preventing thread stripping and ensuring consistent clamping force. The external hex drive accommodates high torque requirements, making it ideal for heavy equipment, structural steel connections, and industrial machinery where reliability is paramount.

Specification Summary & Compliance

This metric hex head screw features M8 x 1.25mm coarse threads with Class 6h thread tolerance for precision fit. The 110mm length includes 22mm minimum thread length with partial threading configuration. Manufactured to ISO 4014/DIN 931 specifications with Class 10.9 strength rating (150,000 psi tensile strength, Rockwell C32 hardness). The zinc yellow-chromate finish provides corrosion protection while maintaining compliance with industrial fastener standards for reliable performance in professional applications.
