Description

The Daggerz® Deck Screw with Ultra-Guard Coating is engineered for long-lasting performance in pressure-treated lumber and outdoor projects. Featuring a durable ACQ-compatible coating, these screws deliver outstanding corrosion resistance while the tan or dark finishes blend seamlessly into most deck boards for a clean, professional look.

Designed for easier driving and a stronger hold, each screw features a star drive with a flat head and nibs that countersink smoothly without damaging the surface. A sharp Type 17 point ensures fast starts, while deep threads provide secure pull-through strength in a variety of decking materials.

Key Features
