Boltight solutions have been at the forefront of the hydraulic tensioning business for many years. The tools feature advanced technology and are designed for critical applications within various industries.

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.


  • 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
