Professional Applications & Engineering Value

These Class 10.9 hex head screws deliver exceptional engineering value in demanding industrial applications where failure is not an option. The zinc yellow-chromate plated steel construction provides superior corrosion protection for outdoor equipment, machinery, and structural assemblies exposed to moisture and chemicals. The M8 coarse thread with 1.25mm pitch ensures rapid installation while maintaining strong clamping force in steel frameworks, automotive components, and heavy machinery. The integrated flange design distributes load evenly, preventing surface damage and reducing assembly time by eliminating separate washers. With Rockwell C32 hardness and full threading, these high-strength fasteners maintain integrity under vibration and dynamic loads, making them ideal for construction, manufacturing, and equipment maintenance applications where reliability is critical.

Specification Summary & Compliance

This M8 hex head screw features precise Class 6g thread fit tolerance and 25mm length with full threading. Manufactured to ISO 898-1 and DIN 6921 specifications, ensuring dimensional accuracy and mechanical properties. Compliant with REACH regulations (EC 1907/2006) for environmental safety. The Class 10.9 strength rating guarantees minimum tensile strength of 150,000 psi with Rockwell C32 hardness for consistent performance in industrial applications.
