Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this M12 hex head screw delivers critical performance where vibration resistance and structural integrity are paramount. The black phosphate steel construction provides essential corrosion protection for machinery, automotive assemblies, and construction equipment exposed to harsh operating conditions. With its flange head design, it eliminates washer requirements while distributing clamp load effectively across joined surfaces. The partially threaded configuration ensures optimal stress distribution along the shank, preventing thread stripping in high-vibration environments. Metric coarse threading (1.75mm pitch) facilitates quicker installation while maintaining superior holding power in steel frameworks, equipment mounts, and structural connections where Class 10.9 strength is mandated by engineering specifications.
Specification Summary & Compliance
Manufactured to ISO 898-1 and DIN 6921 standards with Class 6g thread tolerance for precision fit. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Features 45mm overall length with 30mm minimum thread length, 16mm hex head width, and 26.6mm flange diameter. The right-hand thread direction and external hex drive conform to international metric fastener specifications for industrial applications.
