Product Description

The M1.7×4×0.3 screw is an ultra-compact micro fastener designed for precision applications requiring minimal space and high mechanical stability. With a thread diameter of 1.7mm, length of 4mm, and a fine 0.3mm pitch screw thread, it ensures secure fastening in tight assemblies. Typically constructed from stainless steel or alloy, it offers corrosion resistance and durability in temperatures ranging from -20°C to 120°C. This M1.7 micro fastener is widely used in electronics, miniature devices, medical equipment, and micro-optics due to its lightweight profile and precise thread alignment. Key advantages include reliable torque retention and compatibility with automated assembly systems, while limitations involve handling challenges due to its diminutive size. Specialized tools are required for installation to avoid thread damage. Surface treatments like nickel plating enhance conductivity and wear resistance for industrial applications.
