The HydraNUT is the perfect solution for operations that require quick and regular turnaround. Reactors, Exchangers, Valves, Turbines can all be opened and closed rapidly with this simultaneous bolt loading system.

The HydraNUT is the perfect solution for the application.....

If you do not have a reaction point for a hydraulic torque wrench, a pneumatic wrench, a multiplier, etc.

If you do not have the necessary travel for the handle of a manual torque wrench,

If there is a strong risk of stud-nut seizing,

If the studs or tie-rods are particularly long,

If you need to check the tension in the studs or tie-rods regularly because of vibrations,

If you cannot use a wrench or a multiplier because of the lack of available height or because of restricted space,

If you must ensure overall tightening at 100% of the nominal tension,

If you wish to avoid the phenomenon of stud relaxation,

If the distance between two studs is so small that the nuts are too close to allow sockets to fit over them,

If you want torque-controlled tightening on short studs.

BENEFITS OF THE HYDRANUT SYSTEM
• Reduction of time spent in maintenance stoppages,
• No risk of exceeding the elastic limit of the stud,
• Possibility of approaching the elastic limit of the stud and remaining there while avoiding the phenomenon of relaxation,
• Total tightening simultaneously,
• Immediate and complete tightening in a single action,
• Eliminates friction and twisting,
• Easy to use – quick to set up and to remove,
• Improves safety in working conditions,
• Requires very little physical effort,
• Reliable and precise tension,
• Hydraulic nuts use the strength of hydraulic pressure in order to easily create the forces necessary to efficiently tighten bolts and studs or tie-rods.
