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 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 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”).
