Boltight's hydraulic bolt tensioning tools are used across many industries where traditional torque wrenches cannot be used. Using high pressure hydraulics and a predetermined pressure, Boltight's hydraulic bolt tensioners axially stretch the bolt. The nut is rotated down the joint face, which locks the bolt load and ensures the adequate tightness. The wide selection of equipment also covers high-quality pumps for tensioning tools.
