IPhone lifeproof case problem?

So I took the little screw thing off my lifeproof to put in my earphones and I've seemed to misplace it! Where can I get one cheap and also what would I type in to amazon or something to even find that item?

Well with your life proof case came a small cord you could use so you could plug headphones into it, and the other end goes in the iPhone jack keeping it waterproof. On that cord is another screw. If not just go on eBay and look up life proof case parts or something similar and it should be rather cheap. If you go to "refine" you can set a price range. I put the max at $5 and they range from 1$ to 5$ depending on how many you get.

You could try ebay for cheap cases.
