Model Description

Hydraulic nut / rock type 150MPa Plalad hydraulic nuts do not require tightening tools. Active in "narrow bolts without tools". The hydraulic nut and lock type can "tighten multiple bolts simultaneously and uniformly" by connecting with a hydraulic hose. The bolt tightening work is completed instantly. The tightening axial force of the bolt is uniform and uniform tightened, and there is no frange -tightening. Because bolts are tightened by axial force management, it is possible to tighten higher accuracy than torque management. The hydraulic nut is not twisted, and it is tightened with tensile force, so there is no effect of friction with the seat surface, so you can accurately tighten the bolt because it "hits the bolt directly and axial force".
