Multi-Stage Bolt Tensioner
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.
What are Multi Stage Tensioners?
Multi stage hydraulic tensioners are ideal for applications that are radially limited. They provide a large amount of stroke in a radially compact package by using two or more stages, one on top of the other, both pulling on the same load.
Multi Stage Tensioner Options
HTI multi stage bolt tensioners can be standard or spring return. If one of our standard catalog models doesn’t work, we can design a custom multi stage hydraulic tensioner for any fastening application.
HTI multi-stage tensioners are available in standard sizes (studs up to 6” in diameter) or large stud sizes (up to 16”).

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.
