Professional Applications & Engineering Value
These M12 hex head screws deliver critical engineering solutions for industrial applications where vibration resistance and structural integrity are paramount. The Class 10.9 strength grade combined with black-phosphate surface treatment provides exceptional protection against corrosion while maintaining high clamping force in machinery, structural steel connections, and heavy equipment assembly. The integrated flange design distributes bearing pressure evenly, preventing surface damage and eliminating the need for separate washers - significantly reducing assembly time and part inventory. With fully threaded metric coarse threading and precise Class 6g tolerance, these fasteners ensure reliable engagement in both through-holes and tapped applications, making them ideal for production lines where consistent performance and quick installation are essential.
Specification Summary & Compliance
This M12 x 1.75mm hex head screw features Class 6g thread fit with right-hand coarse threading and full 25mm thread length. Manufactured to ASME B18.2.3.9M specifications with Class 10.9 strength certification. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
