Thrust Point Set Screws

Grub screws with thrust points are used to create a clamping force between two surfaces. The thrust point on the screw head bears against one surface, while the threaded shaft engages the other surface. This creates a frictional force that holds the two surfaces together.

Grub screws with thrust points are commonly used in machine tools, instrumentation, and other applications where precise alignment is required. They are also used in applications where the clamping force must be adjustable.

Here are some of the specific uses of grub screws with thrust points:

• To position and secure components in machine tools, such as lathes, mills, and drill presses.
• To adjust the tension of belts, chains, and other mechanical linkages.
• To hold components in place during assembly or repair.
• To provide a positive stop for moving parts.
• To create a frictional coupling between two surfaces.

The thrust point on the screw head can be either a ball or a cone. Ball-tipped grub screws are more common, as they provide a more uniform distribution of force. Cone-tipped grub screws are sometimes used when a more concentrated force is required.

The size and type of grub screw with thrust point that is used will depend on the specific application. The screw must be strong enough to withstand the clamping force, and the thrust point must be compatible with the surface that it will bear against.
