Product Description

The M2.5x4 machine screws are precision-engineered, small metric screws designed for compact electronic hardware assembly. With a 2.5mm nominal diameter and 4mm length, these M2.5 electronic hardware screws feature ISO-standard threading for secure fastening of PCB components, sensor modules, or low-profile connectors in tight spaces. Typically constructed from stainless steel or zinc-plated steel, they operate reliably across industrial temperature ranges (-20°C to 120°C) and support vibration-resistant connections in consumer electronics, automation systems, and IoT devices. Their compact design enables direct mounting of micro sensors, displays under 3-inch sizes, and battery compartments without occupying excess space. While offering excellent corrosion resistance and standardized compatibility with M2.5 nuts/sockets, their small head requires specialized torque-controlled drivers to prevent stripping. These small metric screws 2.5mm are essential for miniaturized electronics requiring durable, space-efficient fastening solutions.
