Professional Applications & Engineering Value
Engineered for precision and endurance, this M8 metric rounded head Torx screw addresses critical industrial challenges where corrosion resistance, high torque application, and consistent performance are paramount. The 18-8 stainless steel material combined with a passivated finish provides robust protection against oxidation and chemical exposure, making it ideal for machinery, automotive assemblies, and outdoor equipment. The T40 Torx drive minimizes tool slippage, enabling higher torque transfer without damaging the fastener head—essential for automated or repetitive assembly lines. With its fully threaded coarse pitch and Class 6g thread fit, it ensures quick, secure fastening in metals and composites, reducing installation time while maintaining 100,000 psi tensile strength for heavy-duty applications.
Specification Summary & Compliance
This screw conforms to ISO 7380 specifications, with a metric M8 x 1.25 mm coarse thread and Class 6g thread fit for precise dimensional accuracy. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety standards for industrial use.
