For series and service jobs

  • Weight optimized modular design
  • Suitable for on-site use with a maintenance friendly design

Design enables flexible usage

  • For high bolt cycles, series and service jobs, high cycles


  • The hydraulic pumps Hydro-DAX can be used with all ITH torque wrenches (1-hose or 2-hose system). With the ITH torque wrench type CX you can achieve a faster bolting speed by using the 2-hose system with the higher flow rate.

To tighten and loosen multiple bolts at the same time you can connect additional ITH torque wrenches in parallel. All torque wrenches will simultaneously output the same torque (ITH Multi Torquing). This provides an even tension to the joint and decreases the chances of leakage when the joint is used for sealing.
