Our screw and nut machining services combine advanced CNC technology with industry expertise to deliver reliable fastening solutions. Using high-speed CNC lathes, we produce screws with precise thread rolling or cutting, ensuring optimal tensile strength and surface finish (Ra ≤ 3.2μm). Nuts are crafted with accurate thread engagement and anti-loosening designs (e.g., nylon inserts, serrated edges), tested to withstand vibration and heavy loads. Materials can be heat-treated for hardness or plated (zinc, nickel) for corrosion resistance. From tiny M1.6 machine screws for electronics to large M100 foundation bolts for infrastructure, we offer full customization, including non-standard head shapes and special coatings. Rigorous quality control (thread gauge inspection, torque testing) ensures compliance with international standards, making our components ideal for critical applications where safety and durability are paramount.
