The Daggerz Dagger-Deck™ Star Flat Head Screw with Nibs is engineered for exterior wood-to-wood fastening where strength, durability, and clean finishes are essential. Featuring a dark ACQ Ultra-Guard™ coating rated for 1,000 hours of salt spray protection, these screws deliver advanced corrosion resistance and are approved for use with ACQ-treated lumber, making them an excellent choice for decks, fences, and outdoor structures.

For easy installation, the screw includes a flat head with nibs that self-countersink, preventing spin-out and creating a flush, professional finish. A sharp Type 17 point eliminates the need for predrilling and ensures smooth penetration into even dense hardwoods, while coarse threads maximize holding strength. The T-20 star drive provides secure bit engagement, reduces cam-out, and extends driver bit life.
