Product Description

The M2.5*7*4 screws are precision M2.5 machine screws designed for secure fastening in compact assemblies, commonly used in electronics, automation, and small-scale machinery. These M2.5 metric fasteners feature a 2.5 mm diameter, 7 mm shaft length, and 4 mm head height, optimized for space-constrained applications. Compatible with standard M2.5 threading, they provide reliable mechanical connections in modules requiring voltage stability up to 250V and operational temperature resilience from -30°C to +120°C. Ideal for securing PCB mounts, sensor housings, or low-profile enclosures, their corrosion-resistant steel construction ensures durability in industrial environments. While their small size enables high-density installations, they lack load-bearing capacity for heavy-duty use. No integrated electronics, power sources, or screens are included—purely mechanical fasteners.
