Secure Workpiece Easily and Reliably Introducing "Clamping Screws with Eccentric Head"


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.
