Boltight solutions make it possible to tighten and loosen multiple bolts simultaneously using high-pressure hydraulics.
Bolt tensioners stretch the bolt before the nut is wound down under zero friction, ensuring extreme accuracy, speed, uniformity and safety of any bolt tightening situation.

Advnatages
- Tension is applied directly to stretch the bolt, meaning that no friction needs to be overcome
- Applied load is very accurately controlled, as it is directly proportional to the pressure applied to the hydraulic bolt tensioner
- Loss of load between applied and retained load after tensioning is 20% less than frictional loss associated with torqueing
- Accurate residual load outcomes due to calculable load loss
- Tensioning can be repeated
