Clamping Screws

About Screws

Clamping screws are machine elements which use screw thrust for workpiece fixing and positioning.
Point contact by the full ball securely fixes the workpiece.
They include several varieties of tip ball shape and material, which can be selected according to the application.
As well, hex socket head cap screw type clamping bolts have functions similar to clamping screws.
