Hydraulic bolt tensioners apply precise external force to the end of bolts, stretching them to the required length and slightly deforming their diameter. This controlled tensioning method simplifies nut loosening and tightening by eliminating the influence of lubrication conditions and thread friction, providing more accurate bolt loads.

Widely utilized in industries including power generation, shipbuilding, metallurgy, petrochemical, and heavy machinery, hydraulic bolt tensioners significantly enhance work efficiency and safety.
