• A. Self-Locking Screw
• B. Frames
• C. Screw
• D. Wedges

Answer: (C)

Think of a screw as a cylinder wrapped with a helical thread, which can be viewed as a set of inclined planes around the cylinder. When a mate with a matching internal thread (a nut) engages with the external thread, those two threaded surfaces act like two wedges that slide against each other. Turning the screw causes these wedges to ride along one another and convert rotational motion into linear motion along the axis, which is exactly how a fastener works. This is why the component described is called a screw. The self-locking variant is a special case where friction prevents backing out, but the general form described here is simply a screw. Frames and wedges in isolation don’t capture the role of the threaded fastener.
