Professional Applications & Engineering Value
This M3 x 0.5 mm x 8 mm rounded head Torx screw is engineered to address common industrial fastening challenges, such as vibration loosening and corrosion-induced failure. The 18-8 stainless steel material, combined with a passivated finish, provides exceptional resistance to rust and chemicals, making it suitable for electronics assembly, machinery, automotive components, and outdoor equipment. The T10 Torx drive allows for higher torque application compared to Phillips or slotted drives, reducing tool slippage and head stripping. Its fully threaded metric coarse thread ensures rapid installation and robust performance in plastics, sheet metal, and pre-tapped holes, streamlining production while maintaining 100,000 psi tensile strength for long-term reliability.
Specification Summary & Compliance
This screw conforms to ISO 7380 for dimensional accuracy and performance. Thread specifications include M3 size, 0.5 mm pitch, coarse spacing, and Class 6g tolerance for consistent fit. It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it is free of hazardous substances and suitable for use in regulated markets.
