Hydraulic tensioners

Boltight tensioners provide a quick and easy way to tighten bolted joints without the typical challenges of torque tools. Boltight tensioners are a great choice for applications where the accuracy of the bolted joints is critical and small inaccuracies, such as those caused by lubricants, cannot be afforded. Traditional standard tensioners offer a long-lasting and versatile solution for bolt and screw connections in pressure vessels, various manufacturing machineries and oil and gas flanges, for example.

  • Wide range of model sizes – including customized solutions
  • Quick release bridge
  • Improved durability due to specially developed surface coating
  • Long life composite seals

Boltight

Boltight's hydraulic bolt tensioning tools are used across many industries where traditional torque wrenches cannot be used. Using high pressure hydraulics and a predetermined pressure, Boltight's hydraulic bolt tensioners axially stretch the bolt. The nut is rotated down the joint face, which locks the bolt load and ensures the adequate tightness. The wide selection of equipment also covers high-quality pumps for tensioning tools.
