- Systematic Quality Assurance program insures the reliability of
  each fastener that is supplied.
- Riverhawk fasteners operate in critical applications in a multitude
  of applications and industries.

Bolt / Stud Tensioners
- Independent of friction, precluding damage, assuring long life and
  reuse of engineered studs, nuts and bolts.
- Seal system reliability incorporated into each tensioner design.
- Custom tensioners designed to meet specific geometry needs.
- Controlled and accurate pre-loads for reliability and ease of bolt / nut
  installation and removal.
- Reduced down time and man hours.
- Internal and external thread designs available.

Riverhawk Company specializes in hydraulic stud/bolt tensioning products and services, which enable the fasteners in any mechanical joint to be loaded in a controlled and safe manner. In conjunction with our customer's needs, we have developed a full line of hydraulic stud and bolt tensioners for a wide variety of applications and specific geometries by using modern computer aided techniques, including finite element stress analysis.

The tensioners for the engineered studs, nuts, and bolts are made from hardened alloy steel. They are assembled with our seal system that eliminates spiral or twisting failures and has built-in resistance to extrusion. All fittings are supplied to match your installation equipment. All tensioners are pressure tested to ensure against leaks at installation.
