Anyone tried securing with these? http://www.sharkstooth.co.nz/ . Not sure how long they would last for. My pine deck which was nailed with galvanized nails (and boards stayed perfect during that time with no pullouts or warping). It would have been very difficult to replace the topping boards if they had been screwed in. Whereas nails can be pulled out with the right tools. But these connectors look interesting, and no visible connections.
