A CSK head self-drilling screw features a unique head design that tapers down to meet the surface of the material being fastened. This countersunk design allows the screw to sit flush with or below the surface, providing a clean finish. The self-drilling capability stems from a drill-like point, which allows the screw to create its hole as it is driven into the material. These screws are typically made from high-strength steel or stainless steel, making them suitable for various applications.

This action helps to prevent loosening due to vibrations, making wedge bolts particularly advantageous in dynamic environments.
