The Daggerz Dagger-Deck™ Square Flat Head Screw with Nibs is engineered for long-term performance in exterior wood-to-wood applications. Made from 305 stainless steel for excellent corrosion resistance, these screws stand up to harsh outdoor environments, making them ideal for decking, fencing, and other exterior projects.
For a smooth installation, the screw features a flat head with nibs that self-countersink, reducing spin-out and leaving a flush, professional finish. A sharp Type 17 point eliminates predrilling and drives easily into hardwoods, while coarse threads maximize holding power by locking more material between each turn. The 2 square drive provides secure engagement and reduces cam-out for efficient fastening.
