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.

In the aerospace sector, weight reduction is critical. Here, lightweight materials and robust designs come together, providing fasteners that enhance performance without adding unnecessary weight. Double end threaded studs are ideal for mounting fuselages and ensuring structural integrity.
