Professional Applications & Engineering Value
These Class 12.9 steel hex head screws deliver exceptional performance in demanding industrial applications where failure is not an option. The M12 x 1.75mm coarse thread configuration provides superior resistance to vibration loosening while enabling quick assembly in structural steel, heavy machinery, and automotive components. The fully threaded design ensures maximum thread engagement throughout the fastened joint, distributing stress evenly and preventing point loading failures. With 170,000 psi tensile strength and Rockwell C39 hardness, these metric hex bolts maintain integrity under extreme dynamic loads and harsh operating conditions. The external hex drive accommodates high installation torque without cam-out, making them ideal for maintenance-critical applications where reliability and repeatability are paramount.
Specification Summary & Compliance
This M12 hex head screw features Class 6g thread tolerance with 1.75mm coarse pitch right-hand threading and complies with ISO 4017/DIN 933 manufacturing standards. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental compliance requirements. With precise dimensional accuracy maintained throughout production, these 30mm length screws deliver consistent performance across industrial applications requiring high-strength steel fasteners.
