Professional Applications & Engineering Value
These M12 hex head screws deliver critical engineering solutions where high tensile strength and corrosion resistance are paramount. The Class 10.9 steel construction maintains structural integrity under extreme loads, while the corrosion-resistant coating protects against degradation in industrial environments. The coarse thread configuration (M12x1.75mm) enables quick installation and superior resistance to vibration loosening in heavy machinery, construction equipment, and automotive assemblies. With fully threaded design and precise Class 6h thread fit, these metric hex screws ensure uniform load distribution and reliable clamping force across the entire 70mm length, making them ideal for critical structural connections requiring predictable failure margins and long-term durability.
Specification Summary & Compliance
Manufactured to ISO 4017/DIN 933 specifications with Class 6h thread tolerance ensuring precise fitment. The M12 coarse thread (1.75mm pitch) maintains dimensional accuracy per metric standards. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Mechanical properties verified to 150,000 psi tensile strength and Rockwell C32 hardness as specified for Class 10.9 fastener grade.
