HN Hydraulic Nuts

●It is especially suitable for narrow space and heavy-duty vibration mechanical fastening, and can be assembled with multiple bolts at the same time. 

●Adopt no torque design to avoid friction, bolt twisting and other factors that affect the bolt preload, and the tightened bolt is subjected to pure tensile force. 

●The preload can be set accurately, and the accuracy is high.

● With stroke indicator, allowing the amount of stretch to be observed, measured and controlled during operation. 

●Power：198-2450KN. 

●Range：M22-M100. 

●Max pressure: 1500Bar.
