Professional Applications & Engineering Value
This M8 Torx button head screw is engineered to address common challenges in precision assembly, such as fastener failure under vibration and corrosion in demanding settings. The 18-8 stainless steel material, combined with a passivated finish, provides excellent resistance to oxidation and chemical exposure, making it suitable for industrial machinery, automotive components, and electronic enclosures. The Torx T40 drive minimizes tool slippage, allowing for higher torque application without damaging the screw head, which is critical in automated or repetitive assembly lines. With a coarse thread (M8x1.25mm) and Class 6g fit, it ensures quick alignment and secure fastening, reducing installation time and improving overall structural integrity in metric-based engineering projects.
Specification Summary & Compliance
This fastener features a metric M8 thread with 1.25mm pitch and Class 6g thread fit for precise dimensional accuracy. It is manufactured in compliance with ISO 7380 standards for button head screws and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability. The screw is fully threaded, right-hand drive, and includes a rounded button head profile as per standard specifications.
