Product Description

The M2 machine screws, specifically the M2*3 variant, are precision-engineered Electronic assembly screws designed for high-accuracy applications in electronics manufacturing. These Precision M2 screws feature a compact 3mm length with a 2mm diameter, crafted from corrosion-resistant stainless steel or alloy steel with nickel/oxide coatings for durability in demanding environments. They support torque ranges of 0.1-0.3 N·m, ensuring secure fastening in consumer electronics, automotive control systems, and medical device assemblies. Operating reliably across -40°C to +120°C temperature extremes, these screws maintain stability in vibration-prone or moisture-exposed conditions. While offering exceptional thread consistency for PCB mounting and micro-component integration, their miniature size requires specialized drivers to prevent stripping. Common industrial uses include securing sensors, microprocessors, and connector housings where space optimization and electrical insulation properties are critical.
