Professional Applications & Engineering Value

This M8 x 1mm Class 10.9 hex head screw is engineered to address critical challenges in demanding industrial settings, such as machinery assembly, automotive components, and structural frameworks. Made from high-grade steel with a zinc yellow-chromate finish, it combats corrosion and wear, ensuring longevity in humid or chemically aggressive environments. The fine thread spacing and Class 6h fit provide tight, secure fastening that resists loosening under vibration, a common issue in dynamic applications. With a fully threaded right-hand design and external hex drive, it simplifies installation while maintaining high tensile strength and hardness, making it ideal for B2B procurement in sectors requiring reliable, high-performance metric fasteners.

Specification Summary & Compliance

This screw adheres to precise dimensional tolerances, including a Class 6h thread fit per metric standards, ensuring accurate engagement and interchangeability. It meets ISO 8676 and DIN 961 specifications for hex head screws, covering thread size (M8), pitch (1mm), and length (25mm). The manufacturing process complies with industry norms for strength (Class 10.9) and hardness (Rockwell C32), and the zinc yellow-chromate plating aligns with RoHS and REACH directives for environmental safety, providing assurance of quality and regulatory conformity in industrial use.
