Column Screw Rods, Boxes, Nuts, and Check Nuts are essential mechanical components used in industrial machinery to ensure smooth vertical and rotational movement of columns, secure assembly, and precise alignment. Manufactured from high-quality steel or alloy materials, these components provide exceptional strength, wear resistance, and long-lasting durability under heavy-duty operations.These components are widely used in stone processing, CNC machines, milling machines, and other industrial machinery, ensuring accurate column movement, operational stability, and enhanced safety. The combination of screw rods, boxes, nuts, and check nuts allows for controlled motion and prevents loosening during continuous machine operation.
