In modern industry and daily life, precision micro screws are the most inconspicuous yet indispensable basic components. Tiny in size, they are often measured in millimeters or even micrometers in diameter. With stable structure, precise tolerances and reliable fastening performance, they serve as the "industrial joints" that connect everything and support precision operation. From smartphones in

In precision scenarios such as electronic device motherboard fixing, automotive sensor assembly, and medical instrument packaging, micro self-tapping screws have become core fasteners due to their characteristics of self-tapping forming and high-efficiency fastening. The diameter of such screws is mostly between M1-M4, and their thread pitch is 20%-50% larger than that of ordinary screws, enabling
