Foundation Stud & Bolt Tensioners
Hydraulic tensioning is the ideal method for tightening bolted connections. Hydraulic tensioning eliminates inaccuracies and helps achieve correct bolt loading in critical connections. At HTI, we’ve been building hydraulic tensioners and nuts since 1986.
HTI foundation tensioners are designed for the unique constraints of foundation studs for applications such as wind turbine foundations. We can provide tensioning solutions for just about any foundation stud application.
HTI single-stage foundation tensioners provide an economical solution where radial constraints are minimal.
Wind Turbine single stage through-hole foundation tensioner with spring return
HTI multi-stage foundation tensioners provide a radially compact solution where radial constraints exist, such as a close-in neighboring stud distance.
Multi-stage function stud tensioner
Elliptical foundation tensioners provide a compact solution where constraints between the stud and wind turbine mast exist.

Custom Engineered Tensioners Since 1986
HTI has been designing engineered solutions to your toughest bolt tensioning problems since 1986! You can choose from one of our standard catalog sizes above, or we can design a custom fixed tensioner for any application when a standard model won’t work. HTI tensioners can be designed for imperial or metric-sized studs, high loads, high temperatures, large stud sizes, or corrosive environments. Our multi-unit tensioning systems can make easy work of large bolted systems, and our automated tensioning systems can reduce labor and increase throughput in high-volume manufacturing applications.
