Product Description

Designed for precise fastening in compact electronic assemblies, M3x4 machine screws are ultra-small threaded fasteners specifically engineered for securing components on PCBs or thin panels. These Electronics PCB screws feature a metric M3 thread with a 4mm shank length, ideal for low-profile mounting in high-density circuit boards. Constructed from corrosion-resistant steel or nickel-plated materials, they operate reliably across industrial temperature ranges (-20°C to +85°C) and withstand typical electronics operating voltages up to 300V. Widely used in consumer electronics, automotive control modules, IoT devices, and medical equipment, these micro screws for circuit boards enable secure connections between PCBs, heat sinks, and modular components. Their miniature size (3mm diameter head) optimizes space-constrained designs but requires specialized drivers for installation. Compatible with standard M3 nuts and threaded inserts, they provide vibration-resistant fastening for mission-critical electrical connections.
