Product Description

The M2.5x4x6 screws are compact, high-quality M2.5 machine screws designed for precise fastening in applications requiring minimal space and reliable mechanical stability. These M2.5 precision fasteners feature a 2.5mm diameter, 4mm head width, and 6mm shaft length, making them ideal for securing small components in electronics, automation systems, and micro-mechanical assemblies. Constructed from corrosion-resistant steel, they operate effectively in temperatures ranging from -30°C to 120°C and withstand moderate vibration. Their compact design allows direct integration with miniature modules or circuit boards without requiring additional adapters. While they lack electrical interfaces or power connectivity, their primary advantage lies in their durability and precision fit, though over-tightening risks thread damage. Commonly used in robotics, sensor housings, and optical devices, these screws offer a balance of strength and space efficiency for industrial and technical applications.
