Hydraulic External Tensioner

A lightweight, compact and versatile bolt tensioner suited for applications where the bolted joint has a minimum of one stud diameter thread length exposed above the nut. Operates at a maximum pressure of 21,750 psi and utilizes high strength alloy steel components for long lasting performance.

Flange Tensioner

The lightest weight and smallest overall diameter of bolt tensioners in its class. This design features an over stroke stop that prevents seal damage and leakage that also has a visual color coded indicator to identify maximum stroke.

Hydraulic Rod Tensioning System

A tensioner designed to have a smaller foot print and higher preload capability than standard tensioning tools. Typically used on steam and nuclear turbines with limited stud accessibility and no exposed threads above the nut.

Hydraulic Safety Interlock Guard Tensioner

Designed with safety and performance in mind, The hydraulic safety interlock guard is a modular tensioner that is engineered for single user operation and provides full containment of all components during the tensioning process.

Hydraulic Nut

Produces uniform compression of casings, flanges, bearing housings or connection rods and eliminates erratic bolt loads.

Crosshead nut revised

Crosshead Nut

Provides all the features of our standard hydraulic nut, but optimized for extremely high dynamic forces that are typically seen in crosshead applications. 

Hydraulic Tensioned Bolt

Integrates a hydraulic nut into the bolt head which eliminates inaccuracies caused by conventional bolt torquing methods.

External Tensioned Nut

Paired with a bolt tensioner, the external tension nut provides a solution for standard applications in which there are no exposed threads above the existing nut.
