Countersunk Square Drive Ribbed High-Low Thread Spoon Tail Screw (Green Ruspert-Coated)

Product Features
Green anti-corrosion coating: Eco-friendly rust-proof treatment that resists rain, moisture, and chemicals from treated lumber, significantly extending service life in outdoor environments.
Countersunk head + under‑head cutting ribs: Easily cuts into wood during driving, allowing the screw head to sit flush with the surface for a smooth, snag‑free finish while enhancing both aesthetics and corrosion resistance.
Square drive: Prevents cam‑out and stripping, withstands higher torque, and works seamlessly with power tools for greater installation efficiency.
High‑low thread + sharp pointed tip: Enables drive‑in without pre‑drilling; the high‑low thread design reduces driving resistance while providing strong holding power, and also helps prevent wood splitting.
