The Daggerz Dagger-Deck Square Flat Head Screw with Nibs is designed for long-lasting performance in exterior wood-to-wood applications. Featuring a tan ACQ Ultra-Guard coating rated for 1,000 hours of salt spray protection, these screws deliver reliable corrosion resistance and are approved for use with ACQ-treated lumber, making them a trusted choice for decks, fences, and outdoor structures.

For professional installation, the screw includes a flat head with nibs that self-countersink, preventing spin-out and ensuring a flush finish. A sharp Type 17 point eliminates predrilling and penetrates hardwoods with ease, while coarse threads maximize holding power. The #2 square drive provides secure engagement and reduces cam-out during installation.
