From below the head to end of threads. **Q: Will these get surface rust if used for outside?** A: Eventually it will rust as does any steel related product. However it should be quite so time before it does. I live in Tennessee and used these fasteners on my lawn furniture which we get rain and humidity and they have not rusted yet. **Q: The photo of thumbnail is not the flanged button head socket cap screw. what's wrong?** A: This is a good place to look them up.
