Create a better, more beautiful deck with Kreg® Deck Screws and a Deck Jig™. Designed to work with the Kreg® Deck Jig, these superior-quality screws feature a self-tapping tip and aggressive threads for fast, easy driving, plus a smooth upper shank to help pull deck boards tightly against the joist. Case-hardened construction makes them super strong, and a three-layer Protec-Kote™ finish ensures they’ll last outdoors. The small trim-head size and neutral color also makes Kreg Deck Screws great for a variety of other outdoor projects. 51mm length for 25mm and 32mm decking.
