By placing washer 19 between the wastewater treatment equipment and nut 20, and then connecting auxiliary rod 21 to screw body 18 after tightening nut 20, the auxiliary rod 21 is positioned below nut 20, thus limiting nut 20's position. This reduces the risk of loosening or even detachment of the hexagonal step screw due to prolonged vibration during wastewater treatment equipment use. The design effectively limits nut 20's position after connection between screw body 18 and nut 20, preventing it from falling off.
