Boltight® Hydraulic Nuts

Achieve lasting reliability and ensure enduring performance and safety with our hydraulic nuts, ideal for permanent replacement when nuts are needed.

HIGH AND ACCURATE PRELOADS

A hydraulic nut incorporates its own internal hydraulic jack, which enables large diameter bolts to be tensioned to high and accurate preloads. They are quick to install using a hydraulic pump which activates the internal jacking system. The effort required to tighten a very large diameter bolt is reduced to the effort needed to operate the pump, and if an air-driven or electric pump is used, the tightening process is even quicker.

DIRECT REPLACEMENT FOR STANDARD NUTS

Hydraulic nuts are a permanent replacement for standard nuts — and remain on the application after tensioning. As there is no nut rotation during tightening, the operation can be performed in a confined space and torsional stresses or thread damage are eliminated. Learn more about using hydraulic nuts.
