Self-colour Grade 10.9 fasteners have no surface coating or plating. They are in their natural, untreated steel finish after manufacturing.

Grade 10.9 hex head bolts are high-strength fasteners relied upon for their durability and notable performance under load. Its tensile strength is approximately 25% higher than Grade 8.8 bolts, and they are particularly well-suited for dynamic and high-stress applications. Their excellent fatigue resistance makes them ideal for demanding environments across a wide range of industries, including automotive, shipbuilding, construction, engineering, aerospace, railways, and structural steel fabrication.
