Jetnut hydraulic nuts are spun on threaded shafts by hand until snug. Pressure is then actuated hydraulically by a furnished 6 ounce gun. This gun is the only tool needed; sledgehammers, wrenches and hammers that can damage the locking nut are not necessary. Pressure is distributed evenly over the surface because of hydraulic pressure within the nut body.

Hydraulic arbors operate by a displacement principle and by expanding metals within their elastic limits. This expansion is achieved by hydraulic pressure, a true, accurate, and equalized centering force.
