I use this product to hold together birch plywood that was slightly larger than 1/4 and slightly less than 1/2. i can say that they work just as advertised. It will not split wood even if you get dangerously close to the edge. These are quality screws that grab and will not split your wood. The secret is in the tip of the screw according to the spax rep i spoke with at home depot... I love these screws!!!!
Just when you think the torx deck screw is the best thing since sliced bread along comes Spax. I started using the 1 1/2" finish screws a few months ago on hard wood flooring and recently saw the 1 3/4" screws on the shelf so I grabbed them up immediately. I've used them a little bit. They have a little bigger head but they are great !
