Professional Applications & Engineering Value

This M4 x 0.7mm x 40mm 18-8 stainless steel Torx flat head screw is engineered to address common industrial challenges such as fastener failure due to corrosion, stripping during installation, and inconsistent thread fit. The passivated finish enhances the natural corrosion resistance of 18-8 stainless steel, making it suitable for machinery, electronics, and outdoor equipment exposed to moisture or chemicals. The Torx T20 drive minimizes tool slippage, ensuring precise torque application and reducing assembly errors. With a coarse thread and Class 6g thread fit, it provides quick, secure fastening in metals and plastics, while the fully threaded design and 90° countersink angle allow for flush mounting in countersunk holes, improving aesthetics and safety in applications like automotive panels, enclosures, and precision instruments.
