Which advantage does a screw have over a nail?

One advantage of a screw over a nail is the ability to provide a stronger and more secure hold. The threaded design of a screw allows it to grip and engage with the material more effectively, making it less likely to come loose or pull out. Screws are particularly useful in applications where there is a need for increased resistance to withdrawal forces or when joining materials that may undergo movement or vibration. Additionally, screws can be easily removed and reinserted without damaging the surrounding material, allowing for easier repairs or adjustments.
