- Enhanced hardness at Rockwell C32 maintains structural integrity under repeated stress and vibration
Professional Applications & Engineering Value
These M12 hex screws with black-oxide alloy steel construction address critical industrial challenges where vibration resistance and environmental durability are paramount. The fully threaded metric screw design with coarse 1.75mm pitch ensures rapid installation in machinery, automotive assemblies, and structural frameworks while maintaining Class 10.9 strength under dynamic loads. The rounded button head profile provides a low-profile finish that minimizes snagging hazards in confined spaces. Engineered to ISO 7380 standards, these industrial strength screws deliver consistent performance in manufacturing equipment, construction applications, and heavy-duty mechanical systems where high tensile strength and corrosion protection are essential for operational safety and reduced maintenance intervals.
Specification Summary & Compliance
Manufactured to precise Class 6g thread fit tolerances with right-hand threading and 8mm hex drive compatibility. These fasteners meet ISO 7380 specifications for dimensional accuracy and are fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The 35mm length with fully threaded construction ensures consistent performance across industrial applications requiring metric coarse thread fasteners.
