The Daggerz Dagger-Deck™ Composite Square Button Head Screw is engineered specifically for composite decking applications. Made from 305 stainless steel for superior corrosion resistance, these screws withstand harsh outdoor environments, making them a reliable choice for long-term deck performance.
For cleaner results, the screw features a button head design that minimizes mushrooming, ensuring a smooth, professional finish on composite boards. The dual-thread design captures loose material for better countersinking, while the Type 17 point eliminates predrilling and drives easily into dense materials. A 2 square drive ensures secure engagement and reduces cam-out during installation.
