3K-NUT™ is an hydraulic nut for setting  the separator device of rotary shafts.

By using simple T-bar wrench and turning the pressure screw, the pressure piston is pushed, the internally sealed oil is then pressurized to push out the ring piston which then press into position the rotary tools such as spacer and cutter for the slitter machine.  At the same time, the thrust power can be observed by the thrust-power indicator.
Since main body is made of aluminium alloy of one-third the weight of steel, it is very easy to handle for operators.
