There are two main methods for installing decking without visible screws on the surface. You could use hidden deck fasteners, which fit in between your boards and securely fasten boards to your deck frame. Keep in mind that if you use hidden fasteners, you’ll want to buy grooved-edge deck boards. The second option is to use deck board plug systems. With decking plugs, you sink screws through the top of your deck boards and fit a plug on top of the screwhead to fill the hole. We carry plugs made from the same exact material as most decking brands and finishes, so your plugs will exactly match the color and texture of your deck boards.
