Thus, the tool for the operating hexagon isn’t necessary and the high clamping force can be generated by hand. The power boost is generated via the integrated planetary gear.
The automatic switching from preload to power clamping is ensured by the locking mechanism. The very robust design and the self-locking function of the power clamping nuts guarantee a high degree of safety.
The nut is made of heat treated steel, with a housing cover made of high tensile aluminum. The power clamping nuts can be used at temperatures from -30 ° C to + 90 ° C.
