Professional Applications & Engineering Value

This M12 Class 10.9 steel hex head screw delivers exceptional engineering value in industrial applications where vibration resistance and structural integrity are critical. The fully threaded metric bolt design ensures maximum engagement in tapped holes or with nuts, distributing clamp load evenly to prevent joint failure. The external hex drive provides superior torque transmission for high-tension applications, while the coarse thread spacing facilitates quick assembly in production environments. Manufactured from high-grade steel with Rockwell C32 hardness, these fasteners withstand extreme conditions in machinery, construction, and heavy equipment applications without compromising performance. The right-hand thread direction and standardized metric thread form ensure compatibility with existing industrial components and tooling systems.

Specification Summary & Compliance

This hex head screw features precise Class 6g thread fit tolerance according to metric standards, with dimensions of M12 x 1.75 mm pitch x 50 mm length. The fastener meets ISO 4017 manufacturing specifications (equivalent to DIN 933) for dimensional accuracy and mechanical properties. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental safety and restricted substance adherence. The Class 10.9 strength grade confirms high tensile capability suitable for critical structural connections in industrial assemblies.
