Color classification
Grade 12.9 high-strength screws comply with DIN912 standards, featuring a cylindrical head, hex socket drive, knurled design, and M6-M22×1.5 fine threads. Crafted from heat-treated alloy steel, they deliver exceptional tensile strength (≥1200MPa) and shear resistance, ideal for heavy-duty industrial and mechanical applications. The knurled cylindrical head enhances grip during manual installation, while the hex socket drive ensures precise torque control in confined spaces. Fine threads (×1.5 pitch) provide superior load-bearing capacity and stable engagement, making them suitable for precision machinery, equipment assemblies, and high-stress fastening scenarios requiring reliable performance.
