You can get the wood type with a smaller diameter. I use the #9 most of the time since I normally use 2x4 or 2x6s s for my roof supports. It's why I recommended McCoys to Baymule...they are a building supply store and have a much better selection and better employees and they have a store in Mt Pleasant and one in Tyler..
Scroll down to the part where it says "Customers also shopped for" and use the the arrows to scroll across to different sizes. These screws are also self drilling, but use a different type point and they are for drilling thru metal roofing into wood.
