Product Description

The Electronic screws M3x20, commonly referred to as M3x20 PCB mounting screws or M3x20 electronic machine screws, are precision fasteners designed for securing electronic components and modules in industrial applications such as automation, telecommunications, and consumer electronics. These screws feature a 3mm diameter and 20mm length, providing robust mechanical support for PCB installations. Constructed from corrosion-resistant materials like stainless steel or nickel-plated steel, they ensure durability in operating temperatures ranging from -40°C to +85°C. These screws enable direct mounting of power modules, sensors, or communication interfaces onto PCBs, with compatibility for standard M3 threaded inserts. Advantages include high torque resistance, easy installation, and reliable electrical grounding, though their small size may require careful handling in high-vibration environments. Suitable for compact designs requiring secure, space-efficient fastening solutions.
