Hydraulic Stud and Bolt Tensioning Products
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 offers an extensive line of ISO 9001:2015 certified standard hydraulic tensioning systems for stud and bolt tightening. If our standard hydraulic tensioners do not fit your requirements, we can design a custom hydraulic tensioner for any industry and any application.

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.
