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 customers 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 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.
