Hydraulic NutsHydraulic Nuts

Hydraulic nuts replace existing hexagon nuts to give a rapid, accurate and uniform bolt load to any bolted joint. They offer a method of bolt tensioning muli-bolt applications which greatly improves the integrity of the joint. Designed to be as compact as possible, in order to allow adjacent fitment on as many applications as possible. Using multiple hydraulic nuts on a bolted joint gives a much improved uniform bolt load across all bolts.

Benefits

  • Hydraulic connections – User configurable quick release connections. Side and top connections available.
  • Load retaining collar – The tension is permanently retained by means of the load retaining collar.
  • Nut body – Designed with considerable allowable piston movement.

Top & Bottom collar variants available.
