Multi-Unit 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.
With a single tensioner for an application with many studs (or bolts), you still have to apply each bolt-load individually in a pattern that attempts to uniformly load the entire structure; like individually tightening lug nuts on an automotive wheel.
For the ideal uniform loading of a system with many studs, there is nothing better than a system that applies the load to all studs at the same time. HTI makes a wide variety of multi-unit tensioning systems.

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.
