The wedge effect achieves a large clamping force
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.
The screw has a hexalobular socket that can withstand high tightening torque.

Types of Clamping Screws with Eccentric Head
For fixing linear guideway rails and workpieces and tools.
Fixing Linear Guideway Rails
Advantages of using linear guideway rails
- Simple machining
Eccentric head clamping screw holes can be easily drilled, making complicated work unnecessary. Minimizes the amount of mounting space required.
- Reduces mounting time
Unlike methods using C-shaped clamps, the entire rail can be mounted and pressed to a reference surface simply by tightening the clamping screws with eccentric head, enabling quick work. Simultaneously, any warp in the rail is corrected, making it possible to achieve accuracy easily without misalignment occurring when securing the fixing bolts of the rail main body.
- Maintains long-term accuracy
Pressing with clamping screws with eccentric head enables mounting accuracy to be maintained by suppressing the warping and misalignment caused by long-term use.
