Professional Applications & Engineering Value

This M10 hex head screw delivers critical engineering solutions where high tensile strength and corrosion resistance are paramount. The Class 10.9 steel construction with Rockwell C32 hardness withstands extreme mechanical stresses in heavy machinery, structural steel connections, and industrial equipment assembly. The zinc yellow-chromate plating creates a protective barrier against moisture, chemicals, and environmental degradation, significantly reducing maintenance frequency in outdoor or corrosive environments. The metric fine thread design (M10x1.25) provides superior vibration resistance compared to coarse threads, making these fully threaded hex bolts ideal for precision equipment, automotive components, and manufacturing fixtures where loosening under dynamic loads is a concern. The combination of external hex drive and standardized dimensions ensures compatibility with common industrial tools and streamlined installation processes.

Specification Summary & Compliance

This metric fastener features precise Class 6h thread fit tolerance according to ISO metric standards, ensuring consistent threading performance. The manufacturing complies with ISO 8676 DIN 961 specifications for dimensional accuracy and mechanical properties. The zinc yellow-chromate plating meets RoHS and REACH environmental compliance standards while providing corrosion protection. With 40mm length and fully threaded M10x1.25 fine pitch design, this hex head screw maintains strict adherence to international metric fastener standards for reliable integration into global industrial applications.
