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.

Hints for correctly using NBK products

Introducing usage methods for screws with ball-shaped tips for securely fixing workpieces.
