Hydraulic nuts are used to replace critical bolted connections, or connections in places, where no bolt tensioning tools can be used due to lack of space. Hydraulic nuts are tightened simultaneously in order to guarantee a reliable connection. A lot of time can be saved on maintenance by using hydraulic nuts, especially if the nuts have to be sealed with thread protectors, which will protect the nuts against weather, wind and corrosive substances.
