Hydraulic Nuts

Hydraulic nuts replace standard hex nuts in use, offering a fast, accurate and even tightening solution for every bolt connection. The method can be used to tighten several screws at the same time and at the same time ensure a very precise tension of the screws. This is also an unbeatable option for applications where the speed of screw tightening or loosening is important.

  • Long stroke designs
  • Special threads
  • Subsea use
  • Corrosion resistant plating

TensionPro

TensionPro logo header TensionPro's tensioners are used in many industrial applications where it is impossible to use traditional hydraulic, pneumatic or electric torque tools. When using tensioners, the bolted connection is subjected to a purely axial force, and friction, lubrication, lateral loads or other variables causing uncertainty cannot thus impair the tightening result. TensionPro tensioners can also be connected into chains of several tools, which means that a common hydraulics can achieve and ensure a perfectly accurate and smooth result. The quality of operations is also indicated by the ISO9001:2015 certificate.
