Professional Applications & Engineering Value

This high-strength Class 10.9 steel hex head screw delivers exceptional engineering value in demanding industrial environments where fastener failure is not an option. The M10 coarse thread configuration with Class 6g thread fit provides superior vibration resistance and maintains clamping force under dynamic loads, making it ideal for heavy machinery, structural steel connections, and automotive assemblies. The fully threaded design ensures maximum thread engagement throughout the entire 20mm length, distributing stress evenly and preventing localized failure points. With 150,000 psi tensile strength and Rockwell C32 hardness, these metric hex bolts withstand extreme mechanical stresses while the external hex drive facilitates quick installation with standard tools, reducing assembly time and labor costs in production environments.

Specification Summary & Compliance

This precision metric fastener features M10x1.5 coarse threading with Class 6g thread tolerance and right-hand thread direction, manufactured to exacting ISO 4017 and DIN 933 specifications. The 20mm length and 17mm hex head dimensions maintain tight dimensional control for consistent performance. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance, while the Class 10.9 strength classification guarantees mechanical properties meet international standards for high-strength fasteners.
