When the screw is tightened, the workpiece is strongly clamped by the head, which is decentered from the shaft center of the screw.
The wedge effect creates a large clamping force with low tightening torque.
Suitable for fixing linear guideway rails.
As the decentered head presses the linear guideway rail against the installation reference surface, precision can be easily achieved when mounting.
Also, mounting accuracy is maintained by suppressing warping and misalignment caused by long-term use.
