Professional Applications & Engineering Value
Engineered for demanding industrial environments, these Class 10.9 hex head screws deliver exceptional performance where vibration resistance and structural integrity are critical. The black-phosphate steel coating provides superior corrosion protection without compromising the 150,000 psi tensile strength, making them ideal for automotive assemblies, heavy machinery, and structural frameworks. The flanged design per DIN 6921 distributes clamping force evenly, preventing surface damage while the M6 coarse thread ensures rapid installation in production lines. With partial threading and Rockwell C32 hardness, these fasteners maintain thread integrity under dynamic loads, solving common failure points in vibration-prone applications while meeting rigorous industrial standards.
Specification Summary & Compliance
Manufactured to exacting ISO 898-1 specifications with Class 6g thread fit tolerance for precision engagement. The M6 x 1 mm coarse thread configuration ensures compatibility with standard metric components. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming adherence to international substance restrictions. The DIN 6921 standard governs the flanged hex head dimensions and mechanical properties, guaranteeing interchangeability and consistent performance across industrial applications.
