Product Description

The Electronic screws M4x9 are precision-engineered M4x9 electronic hardware components designed for secure fastening in PCB assembly and electronic device manufacturing. These PCB M4 machine screws feature a 4mm diameter and 9mm length, providing robust mechanical stability for mounting components, connectors, or modules onto circuit boards. Constructed from corrosion-resistant materials, they operate reliably in industrial environments (-20°C to +85°C) and withstand typical PCB operating voltages up to 600V. Widely used in automation, telecommunications, and embedded systems, these screws ensure vibration-resistant connections while maintaining electrical isolation. Their compact design minimizes space requirements in dense electronic layouts, though installation requires proper torque control to prevent PCB damage. Compatible with standard M4 nuts and tools, these screws comply with IEC 60950 safety standards for electronic hardware.
