Zinc Large Diameter Concrete Screws for Heavy-Duty Interior Anchoring

Zinc-plated large diameter concrete screws are built for high-load anchoring in concrete, block, and brick where strength and speed matter. Designed for structural and equipment connections, these heavy-duty screw anchors provide strong mechanical engagement without the need for expansion sleeves or wedge-style anchors.

Reliable Strength for Dry and Low-Moisture Environments

The large diameter design increases surface contact within the base material, delivering strong shear and pullout performance for framing, ledger attachment, racking systems, and machinery installs. Zinc plating adds a layer of corrosion protection, making these anchors a cost-effective solution for interior or lightly sheltered exterior applications.

Installation is straightforward. Drill the proper pilot hole, clean out debris, and drive the anchor to the recommended embedment depth for a secure hold.

Common Applications

  • Ledger board attachment to concrete foundations
  • Structural brackets and base plates
  • Warehouse racking and equipment anchoring
  • Commercial framing and retrofits

Key Considerations

  • Environmental Exposure: Best suited for dry interior or low-moisture environments.
  • Load Requirements: Confirm shear and tension values meet project specifications.
  • Base Material: Designed for solid concrete and grout-filled block.
  • Proper Installation: Use the manufacturer-specified drill bit and follow embedment guidelines.
