#8 x 3 in. Exterior Deck Screws – 1 lb. Box (Model 42677) – 10‑Year Coated Phillips Drive
The Model 42677 #8 x 3 in. Deck Screws are engineered for reliable, long‑lasting fastening in exterior wood construction. Built with a durable 10‑year weather‑resistant coating, these screws guard against corrosion, moisture, and harsh outdoor exposure—making them ideal for pressure‑treated lumber and general exterior installations.
With their balanced #8 gauge thickness and extended 3‑inch length, these screws provide strong holding power without overly stressing thinner or softer wood materials. Their coarse deep‑cut threads grip wood fibers securely, while the sharp fast‑start point ensures smooth penetration and reduces splitting. The Phillips drive head delivers steady bit engagement for efficient fastening. Packaged in a compact 1‑lb box, this size is perfect for repairs, small‑to‑medium projects, or topping off fastener inventory.
