As it was told to me:

“the interesting thing about that puncture… the screw was 50% longer than what you see… instead of just pulling out, I knew I still had 7 miles to get home… so I unscrewed the screw from the tyre… kept the hole itself small… put a new tube in and safely rode home.”

No amount of puncture resistance is going to stop a screw like that.
