Hex Drive Hydraulic Torque Wrenches for Bolt Tightening Operations

The NSX series is the “go-to” wrench when standard industrial torque tools are limited by size in their ability to engage the fastener. The NSX eliminates issues around the nut, behind the nut and above the nut. On applications with extended stud protrusion, the NSX easily slips over to get the torque applied with an accuracy of +/-3%.

When to use an Hex Drive Torque Wrench?

Hydraulic hex wrenches are ideal when it comes to deal with torque bolting in confined spaces or with limited spaces available. This tool is definitely the right choice. When there is not enough space in the access areas surrounding the nut, a hydraulic wrench with reduced dimensions must be used. The accuracy of the applied torque is +/- 3%.

How do I choose the right tightening torque?

Check the following table to view the tightening torque of each model of hydraulic wrench. Each model has its own torque conversion table.

How is it powered?

The hydraulic torque wrenches are powered by two types of power units, namely by electric power units and pneumatic power units. Ask us for more information!

What are the other models of hydraulic wrenches?

In addition to hex drive hydraulic wrenches, hydraulic wrenches with square drive are also available, which require the use of sockets in order to be used. Click on the box below for more information.
