Which term best describes a screw that can tap its own hole when integrated into the material?

• A. Self-tapping screws
• B. Threaded fasteners
• C. Riveting
• D. Adhesives

Answer: (A)

Self-tapping screws can form their own mating threads in the material as they are driven, either by cutting or forming the threads in place. This means they don’t require a pre-tapped hole; the screw’s tip and thread shape create the threaded path while tightening. That capability is why this term fits best. Other options describe different joining methods: threaded fasteners is a broad category, riveting joins by deforming material, and adhesives bond surfaces without forming threads.
