1) The pre-tightening force of the DN/HN hydraulic nut can be accurately set, and its accuracy can reach ±3%. It can also operate normally under a pressure of 150MPa, and its accuracy and quality are beyond doubt.
2) DN/HN hydraulic nuts adopt pure tension to fasten the bolts when tightening the bolts. No torque is applied during the tightening process of the bolts, thus avoiding friction, bolt deformation, bolt pre-tightening force and other factors that affect the precise tightening of the bolts, ensuring the efficiency and quality of construction.
3) DN/HN hydraulic nuts are very suitable for bolt tightening of heavy-duty vibration machinery, which can prevent the bolts from loosening due to long-term vibration and causing accidents, such as vibration motors, warehouse wall vibrators, heavy-duty vibrating screens, etc.
4) DN/HN hydraulic nuts are easy to use and simple to operate. It is equipped with a stroke indicator, which can be observed, measured and controlled at any time during the operation process to improve work efficiency and construction quality.
5) DN/HN hydraulic nuts can be packed in double layers, aluminum-plastic box plus wooden box. TorcStark stocks a large number of DN/HN hydraulic nuts, which can be shipped immediately. The transportation time depends on the transportation method, and the shortest time is 3-5 days. TorcStark provides a one-year product warranty service.
