Hydraulic Nuts are used in direct replacement of the existing conventional nut.
They allow accurate loading of the bolt, and the load is then permanently retained by means of a load locking collar.
Hydraulic nuts are quick and simple to use. Installed by hand in minutes, multiple nuts are harnessed together to give IMPROVED SPEED for the bolt tightening process. The even joint compression ensures uniform bolt loading and gasket compression that gives superior bolted joint performance.
