  • Unique Metal to Metal Seal Design
    - Tolerant to harsh environments
    - Applications up to 500°F and higher
    - Water charged for special application
  • Multibolt Tensioning
    - Simultaneous "Daisy Chaining" provides uniform clamp loads and shorter assembly time.
  • Compact Standard Sizes
    - Accommodates confined spaces and envelope restrictions.
  • Inherent Safety
    - Forces act along bolt axis and not thought torque reaction arms.

Riverhawk Hydraulic Tensioned Nuts (HTN) and Bolts (HTB) eliminate conventional bolt load torquing inaccuracies occurring from stud twisting and friction losses at the nut face and thread interfaces. The Riverhawk HTN & HTB eliminates this torquing friction, thereby improving the integrity of the joint. The compact standard sizes of the Riverhawk HTN and HTB are ideal for confined spaces or where envelope restrictions prevail.

Whether you tension one bolt or many bolts at a time, the Riverhawk HTN and HTB produces uniform compression of casings, flanges, bearing housings or connection rods. In addition, the improved tensioning repeatability of the HTN will eliminate excessive and erratic bolt loads.

Any number of Riverhawk HTN's and HTB's can be connected together and loaded simultaneously. This multibolt tensioning serves to appreciably shorten assembly or maintenance time. In addition, the HTN and HTB allows for a minimal number of operators. All together, this provides for quick and easy installation which relates to cost savings.
