The Exciting Life of a Phillips Head

Since there are approximately 70 billion types of screws ( don't quote me on that one, I have a tendency to exaggerate) I figured I should do a little research on the type I'm using. I found a website which sells all sorts of building supplies and was able to give me a product catalog of wood screws. Below is all of the wood screws, and then the Phillips head, which is what I will use.
