Stainless Steel Large Diameter Concrete Screws

Stainless steel large diameter concrete screws are built for the toughest environments, combining maximum anchoring strength with the highest level of corrosion resistance. Ideal for coastal, chemical, or high-moisture applications, these heavy-duty fasteners are designed to perform where zinc or galvanized coatings fall short.

Use them for structural supports, heavy equipment anchoring, marine applications, or food-grade environments where rust simply isn’t an option. The large diameter design delivers superior holding power, and the stainless construction ensures long-term integrity under pressure.

  • Corrosion-Proof: Stainless steel resists rust in harsh and wet environments
  • Structural Strength: Heavy-duty threads grip securely in concrete, block, or brick
  • Long-Term Reliability: Ideal for critical anchors in exposed or demanding conditions

Available in multiple sizes to meet code and project specs. Most orders placed before 4:00pm CST ship the same day from our centrally located warehouses.
