The Hillman 47219 #12 x 1" Self‑Drilling Hex‑Washer‑Head Screw is a heavy‑duty fastener built for reliable performance in metal, wood, fiberglass, and other construction materials. Its integrated drill‑point tip allows the screw to bore directly into thin‑gauge steel and similar substrates without requiring a pilot hole—saving time, reducing labor, and ensuring consistent installation.
These screws feature a zinc‑plated steel body for moderate corrosion resistance, a stable hex‑washer head for controlled driving, and sharp threads designed to tap clean, strong mating threads in the material during installation. Packaged in a 1‑pound box, this product is ideal for professional contractors, metal‑building installers, roofers, HVAC technicians, and do‑it‑yourself users who require durable fastening power.
