Bill, I have never heard of this fastener and with Jay's link, I zoomed over there to get up to speed.
Bill, this sounds good, but I have several questions: 98% of my decks are made of PT wood. This wood is full of chemicals when wet and it does require special tools to handle this friction. But, when the wood dries out, it becomes very attractive and functional.
My point is you would ruin your biscut cutter very quickly with all the stuff in the wood. I know how expensive a biscut cutting blade is.
Secondly, I like decking boards that are screwed down for good fastening and for easy removal when you need or want to change out a board.
Alot of my business is not a complete deck, but to re surface if you will the decking only. How can this occur with this system?
Then Bill, I try to keep my material costs to a bare minimum when constructing a deck and also things that will bog down my construction time. This seems like quite an additional amount of man hours to install.
I like decks with joists every 16 or 18 inches. This would require many of these fasteners.
Bill, If you would get some zinc coated or galvanized screws with allen fittings and sink them just below the surface and then spray the finished deck with water, the wood will go over the screws and you will not see then again. But, you will know where they are if needed.
Bill, I am not trying to shoot down your idea or new fastener system, I am just being the devil's advocate on some things.
I just thought of another thing. Have you ever used a biscut cutter and joined two boards together? You know boards have different particularities that make doing this difficult, for example, many 2x6's are not the same height. Many have wanes, many have bows, these traits would be very difficult to align and join together two boards not to mention 25 or 30 side by side.
I would never consider this, because there is no such thing as two cloned boards of the same size.
