Zinc Large Diameter Concrete Screws

Zinc-plated large diameter concrete screws deliver heavy-duty anchoring performance in concrete, block, and brick, ideal for structural connections, framing, or equipment installs. The zinc finish provides basic corrosion resistance, making these screws a cost-effective solution for dry interior or lightly sheltered exterior environments.

Use these anchors when you need high load capacity and fast, direct installation without the need for sleeves or wedge anchors. Common in commercial builds, machinery setups, and ledger board mounting.

  • Heavy-Duty Hold: Large diameter design handles structural loads
  • Zinc Plating: Resists corrosion in dry or low-moisture environments
  • Quick Install: Self-tapping threads cut directly into concrete or block

Choose from multiple lengths and head styles to match your project needs. In stock and most orders ship same day when ordered before 4:00pm CST.
