What are clamping screws?

Clamping screws are mechanical 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.

Advantages of using clamping screws

By replacing hex socket head cap screws and hex socket set screws with clamping screws or clamping bolts when clamping (fixing) workpieces, point contact with workpieces can be achieved. This effectively transmits force to the workpiece and keeps the clamp secure.

As well, when clamping inclined workpiece surfaces, use the flat ball type in order to allow the tip ball to rotate freely, so that the ball flat surface makes surface contact with the workpiece inclined surface, achieving secure clamping.

Usage examples of clamping screws

For workpiece fixing.

For tool fixing.

Less time and trouble spent on manufacturing workpiece fixing jigs and maintenance

When fixing the workpiece by clamping its inclined surface, the jig body must be machined to match the workpiece shape.
However, with clamping screws, the jig body just needs screw threading. Jig body shapes can be made more simple.
In addition, if the workpiece contact surface wears, just replace the clamping screw. The time and trouble of maintenance is reduced.
