Product Description

The M6x40 electronic screws are precision-engineered M6 40mm machine screws designed for secure fastening in high-precision electronic assemblies and industrial equipment. These M6-40 threaded fasteners feature a durable stainless steel construction with corrosion-resistant coating, ensuring reliable performance in environments with temperature ranges from -20°C to +120°C. Ideal for applications in automation, telecommunications, and robotics, they provide robust mechanical stability for direct module-to-chassis mounting or inter-component connections. The 6mm diameter and 40mm length enable versatile compatibility with standard panel cutouts and mounting frameworks. Key advantages include vibration resistance and RoHS compliance, while limited thermal expansion under extreme conditions may require supplemental locking mechanisms in dynamic settings.
