Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M12 hex head screws deliver exceptional performance in machinery assembly, structural frameworks, and precision equipment manufacturing. The Class 8.8 steel construction provides reliable strength for heavy-duty fastening, while the extra fine metric thread (1.25mm pitch) offers superior resistance to vibrational loosening - a critical advantage in dynamic operating environments. The zinc plated finish creates an effective barrier against corrosion, significantly extending service life in challenging conditions. With full threading along the entire 40mm length, these metric fasteners ensure maximum thread engagement and uniform load distribution, making them ideal for applications requiring consistent clamping force and structural integrity.
Specification Summary & Compliance
This fully threaded hex head screw features M12 x 1.25mm extra fine threads with Class 6h thread fit tolerance, ensuring precise mating with corresponding nuts and threaded components.
