Key Advantages

Enhanced Safety

The neat hydraulic operation takes the place of old manual torque tools, making the job safer for the operator and giving a force you can count on and control.

Precision & Speed

The hydraulic preload gives a consistent force faster than the usual torque methods, cutting down assembly time and boosting how good the joint is.

Compact & Adaptable

Their lean design fits nicely even in tricky spots with lots going on overhead. The shim-type versions make sure you get low preload loss, and they self-align even when there's not much space around.

Thread Preservation

Since hydraulic tensioning uses axial force instead of twisting torque, the bolt threads stay in good shape, helping durability and fatigue resistance.

HFHN Hydraulic Nuts serve as a direct replacement for conventional nuts. They enable the accurate loading of the bolt, and the applied load is permanently retained through a load-locking collar.

HFHN Hydraulic Nuts prioritize safety with features such as CE marking, a safe over-stroke device, a max stroke indicator, and pressure test certification. The comprehensive safety measures contribute to reliable performance.

HFHN Hydraulic Nuts incorporate the latest seal technology, ensuring a high cycle life and an optimized load-to-weight ratio. The integration with HexForce pumps and hoses further enhances their technological capabilities.

HFHN Hydraulic Nuts offer a range of options, including thread sizes from M22 to M150, imperial or metric designs, configurations for special load requirements, variations for different temperatures, subsea use, long stroke designs, single or twin ports, corrosion-resistant plating, and stainless steel versions. This versatility caters to diverse application needs.

HFHN Hydraulic Nuts are quick and simple to use, allowing for manual installation in minutes. When multiple nuts are harnessed together, they enhance the speed of the bolt tightening process. The even joint compression ensures uniform bolt loading and superior performance in bolted joints.

HexForce hydraulic nuts allow bolts to be loaded with an accurate force directly proportional to the pressure applied to the tool. This achieves pure axial loading, eliminating friction during bolt tightening and ensuring an accurate and repeatable method.

A hydraulic nut is designed to facilitate the controlled and uniform application of tension to bolts during assembly. It uses hydraulic force to stretch the bolt, ensuring even clamping force.

Hydraulic nuts are used to mount and dismount bearings. To use one, you place the hydraulic nut over the shaft, apply hydraulic pressure to the piston, and the nut expands, creating a controlled force to facilitate the installation or removal of bearings.

The pressure on a hydraulic nut can vary depending on the application and size of the nut. It is typically specified by the manufacturer and should be within the recommended range to ensure safe and efficient operation.

Hydraulic nuts provide a controlled and uniform force, making the process of mounting or dismounting bearings more precise and efficient. This helps prevent damage to the bearings and ensures proper alignment.
