Professional Applications & Engineering Value
These M12 hex head screws with black-oxide steel construction deliver exceptional performance in industrial settings where corrosion resistance and vibration management are critical. The flanged design eliminates the need for separate washers while providing superior clamping force distribution, making them ideal for machinery assembly, structural frameworks, and automotive applications. The combination of Class 6g thread fit and fully threaded configuration ensures maximum thread engagement in both thick and thin materials, while the serrated locking feature maintains joint integrity in high-vibration environments. With metric coarse threading (1.75mm pitch), these fasteners provide quick installation and reliable performance in production lines where efficiency and durability are paramount.
Specification Summary & Compliance
Manufactured to precise metric dimensions with M12 x 1.75mm coarse threads meeting Class 6g tolerance standards for consistent fit and performance. The black-oxide steel construction provides both corrosion protection and an attractive finish while maintaining Rockwell C27 hardness and 130,000 psi tensile strength. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
