To obtain accurate and reliable tension, replace existing nuts with Riverhawk Hydraulic Tensioner Nuts (HTN).

Hydraulically Applied Tension Produces:
accuracy, reliability & repeatability

improved joint integrity, eliminates torquing friction

uniform compression - casings, flanges, bearing housings or connecting rods

improved tensioning - eliminates excessive/erratic bolt loads

Compact Standard Sizes
accommodates confined spaces and envelope restrictions

Multibolt Tensioning
shortens assembly/maintenance time

minimizes number of operations

quick & easy installation - saves cost

Inherent Safety
forces at play act along the axis of the bolt, not through any hazardous torque arms

Unique Metal to Metal Seal Design
tolerante to harsh environments particularly suited for applications up to 500°F

Note: In the event a standard product will not satisfy a given application, Riverhawk will either modify the standard product or custom design a solution.
