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.
Asked by: Poetrkc
You can use them but remember screws are a harder metal than nails and are brittle. I don't think they will pass any codes for framing, but they will suck in some warped boards that nails won't touch. I will use them together to get everything tight.

How well to they stand up to corrosion? Do they have a corrosion warranty?

How well to they stand up to corrosion? Do they have a corrosion warranty?
Asked by: neilfcars
Absolutely. I use them for outdoor furniture, decks and fences. They never stain the wood like some types of screws.
