A hydraulic bolt tensioning tool provides a quick, easy and safe method for tightening large diameter bolts to high and accurate preloads. It does not use torque or require forceful turning of the nut or bolt, like impact wrenches, flogging spanners or hydraulic torque wrenches, where friction is a common enemy.
Boltight hydraulic tensioners are engineered to go above and beyond industry safeguards. Each tensioner has built-in fail-safe measures and are rigorously tested prior to shipment. When safety really matters, choose a Boltight hydraulic tensioner.
