Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M10 hex head screws with Class 8.8 strength rating provide exceptional reliability in machinery assembly, structural frameworks, and heavy equipment. The zinc-plated steel construction offers superior corrosion protection while maintaining the 110,000 psi tensile strength required for high-stress connections. The serrated flange design creates positive locking action that prevents loosening under vibration, eliminating the need for additional locking components. With coarse M10x1.5mm threading and Class 6g thread fit, these fully threaded metric bolts ensure rapid installation and consistent clamping force across various material types, making them ideal for production lines where efficiency and reliability are critical.
Specification Summary & Compliance
These hex head screws feature M10x1.5mm coarse thread with Class 6g thread fit and 20mm length, manufactured to DIN 6921 standards for dimensional accuracy and performance consistency. The Class 8.8 strength grade ensures mechanical properties meet international requirements for medium-duty applications. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmental safety and restricted substance control for global industrial use.
