Professional Applications & Engineering Value
Engineered for precision and reliability, these M8 flat head screws address common industrial challenges such as joint failure and corrosion. The black-oxide alloy steel construction provides a protective layer that resists rust and wear, making them suitable for machinery, automotive assemblies, and structural frameworks exposed to moisture or chemicals. With a Class 10.9 strength grade and coarse thread pitch, they ensure quick assembly and high clamp force, reducing the risk of loosening under dynamic loads. The fully threaded design and 90° countersink enable seamless integration into metal or composite materials, offering a flush finish that minimizes protrusion and enhances safety. Ideal for industrial fastening where durability and compliance with international standards are critical.
Specification Summary & Compliance
This screw features M8 x 1.25mm coarse threads with a Class 6g tolerance for precise fit, and is manufactured to DIN 7991/ISO 10642 specifications. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material restrictions are met for global supply chains.
