Can these screws be used in framing as in sheds and small portable type cabins? I used them on a pen i'm building for goats and I am sold on these the only thing that I experienced was minor chipping on the surface of the wood. I love these screws just making sure I can use them in framing before I plan out my new project. Thanks.
