IU-XL Series

Hydraulic bolt tensioning provides a quick and easy method for tightening large diameter bolts.

Tensioners are known for being extremely accurate. Completely covering the nut and the bolt, the tensioner is pressurized, the bolt is stretched, and then the nut is turned to retain the tension on the bolt. They can also be hydraulically linked together across multiple bolts, giving you an even faster, more accurate preload.

They also eliminate the need to replace nuts and washers due to wear and tear.
