Professional Applications & Engineering Value

These M16 flat head screws are engineered with black-oxide alloy steel to address critical industrial challenges such as vibration loosening and environmental degradation. The fully threaded metric coarse pitch design ensures maximum thread engagement in soft materials and quick assembly in high-volume production lines. With a Class 10.9 strength rating and 120,000 psi tensile strength, they provide reliable performance in heavy machinery, structural steel connections, and automotive assemblies where fatigue resistance is paramount. The flat head profile creates flush surfaces in countersunk applications, while the 10mm hex drive accommodates standard torque tools for efficient installation in confined spaces.
