Professional Applications & Engineering Value
This M12 hex head screw delivers critical engineering value through its Class 10.9 steel construction and zinc yellow-chromate plating, addressing common industrial challenges like joint failure and corrosion. The partially threaded design with coarse pitch provides superior clamping force in structural applications, machinery assembly, and heavy equipment where vibration resistance is paramount. With 150,000 psi tensile strength and precise Class 6h thread fit, it eliminates loosening in dynamic loads while the external hex drive enables quick installation in confined spaces. Ideal for automotive, construction, and manufacturing sectors requiring metric coarse thread fasteners that meet ISO 4014 specifications for reliability.
Specification Summary & Compliance
Manufactured to ISO 4014/DIN 931 standards with Class 6h thread fit tolerance and M12 x 1.75mm coarse pitch threading. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety. The 55mm length with 30mm minimum thread length provides consistent engagement, while the Rockwell C32 hardness and 150,000 psi tensile strength verify mechanical performance for industrial use.
