Professional Applications & Engineering Value
These M12 hex head screws deliver critical engineering solutions for heavy-duty industrial applications where vibration resistance and structural integrity are paramount. The Class 8.8 steel construction provides reliable performance under extreme loads, while the zinc plating offers essential corrosion protection in harsh environments. The partially threaded design allows for precise load distribution, making these metric fasteners ideal for machinery assembly, structural steel connections, and equipment manufacturing. With coarse threading and external hex drive, installation efficiency is maximized while maintaining the high tensile strength required for critical joints that cannot compromise on safety or durability.
Specification Summary & Compliance
Manufactured to exacting ISO 4014 and DIN 931 standards with Class 6h thread fit tolerance for precision engagement. These metric hex head screws feature M12x1.75mm coarse thread configuration with right-hand threading and 30mm minimum threaded length. Full compliance with ISO 898 mechanical properties, RoHS 3 (2015/863/EU) environmental directives, and REACH (EC 1907/2006) chemical regulations ensures international acceptance for industrial and construction applications.
