Daggerz ACQ Dagger #10 x 4″ Exterior Wood Screw – Square Flat Head, Tan Ultra-Guard (1,000 Pack)

The Daggerz ACQ Dagger Square Drive Exterior Wood Screw is designed for wood-to-wood fastening in exterior applications, including ACQ pressure-treated lumber. Manufactured from C1022 low carbon steel, it features Dagger Ultra-Guard Coating, a multi-step zinc/chromate and proprietary organic coating system that provides 1,000-hour salt spray corrosion resistance for long-lasting performance in demanding outdoor environments.

The Type 17 point provides fast starts and efficient penetration into wood, while the flat head allows the screw to countersink cleanly for a flush finished appearance. The square drive provides positive bit engagement during installation and helps reduce cam-out compared to conventional drive styles.
