Hydraulic Nuts

The Hydraulic Nut is a permanent fixture, replacing the conventional nut and retaining the high bolt load and extension in small space envelopes where there may not be sufficient space to use tensioners. The nut can be retrofitted to existing plant and is a simple and accurate solution to mechanical jointing problems.

All bolt tensioning systems can be retrofitted with the vacuum retract tensioner.
