Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M12 hex head screws combine hot-dipped galvanized steel construction with Class 10.9 strength to solve critical fastening challenges. The partial threading design with 57mm grip length prevents joint loosening in high-vibration environments like machinery, structural steel connections, and heavy equipment assembly. The coarse thread pitch (1.75mm) enables quick installation in steel frameworks and construction projects, while the external hex drive provides superior torque transmission compared to internal drives. With 150,000 psi tensile strength and Rockwell C32 hardness, these metric screws withstand extreme loads without deformation, making them ideal for automotive, manufacturing, and infrastructure applications where failure is not an option.

Specification Summary & Compliance

This M12 x 1.75mm hex head screw features Class 6g thread tolerance for precision fit and coarse thread spacing per metric standards. Manufacturing complies with DIN 6914 and ISO 7412 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets.
