The Hillman Deck Plus #8 x 2" deck screw, identified by manufacturer code 48709, is a carbon steel fastener designed for exterior wood construction. It features a green ceramic coating that provides superior rust and corrosion protection, confirmed to withstand over 1000 hours of salt spray and suitable for use with ACQ, CA, and CCA treated lumber. The screw is equipped with a Star Drive (also referred to as Dual Torq Drive by Hillman, often a T25 Torx) to prevent cam-out during installation. It has a coarse thread for strong holding power and a self-drilling sharp point, often Type 17, which enables penetration without pre-drilling and helps prevent wood splitting. The flat head includes nibs or cutting ribs to ensure a clean, flush countersunk finish. These screws are ideal for securing decking boards, fences, and other outdoor timber structures. A matching T25 Star drive bit is typically included in the package.
