The HexForce standard lineup presents versatile and reliable hydraulic tensioners tailored to a wide array of bolting tasks. Primed for topside operations, they shine in tightening commonly utilized flanges such as ANSI, ASME, and API standards. A tensioner is a device that applies a force to create or maintain tension. The force may be applied parallel to, as in the case of a hydraulic bolt tensioner, or perpendicular to, as in the case of a spring-loaded bicycle chain tensioner, the tension it creates.
