About Hydraulic Tensioners

Hydraulic bolt tensioners are hydraulic tools used to tighten studs by stretching. After the stud has been stretched, the nut is rundown to the joint. The load on the stud is removed, which results in a clamping force transferred to the now bolted joint.

Different applications call for different types of hydraulic stud tensioners. Hydraulics Technology offers hydraulic tensioning solutions for a range of applications in the mining and medical industries, as well as environmental cleanup. At Hydraulics Technology, our team can help you find the right tensioner to fix your stud and bolt tightening problems. HTI’s variable, fixed, subsea, wind turbine, and pump coupling tensioners are designed to work with other HTI tools and come in a range of operating capacities.
