Product Description

The M2x4 electronic screws, a type of miniature machine screws, are precision-engineered PCB mounting hardware screws designed for securing compact components in electronics. With a 2mm diameter and 4mm thread length, these screws feature corrosion-resistant steel or nylon construction, supporting operating temperatures from -40°C to +120°C. Ideal for low-voltage PCB assemblies, they enable direct mounting of modules in consumer electronics, IoT devices, and industrial automation systems. Key advantages include space-efficient design, vibration resistance, and compatibility with standard M2 nuts, though their small size may require specialized drivers for installation. These screws accommodate tight layouts without protruding hardware, ensuring reliable connections in high-density circuit board applications. (398 characters)
