Galvanized Large Diameter Concrete Screws

Galvanized large diameter concrete screws offer heavy-duty anchoring strength with enhanced corrosion resistance, making them a smart choice for outdoor and exposed applications. The mechanical galvanized coating provides solid protection against rust, especially when fastening to treated lumber or working in semi-exterior environments.

Perfect for structural connections, deck ledger boards, racking systems, or mechanical installations that demand both holding power and weather durability. These self-tapping screws eliminate the need for anchors, saving time on the job while still meeting building code requirements.

  • Corrosion-Resistant: Galvanized finish stands up to moisture and treated wood contact
  • High Load Capacity: Large diameter threads provide a secure hold in concrete or block
  • Code-Friendly: Suitable for many structural and outdoor framing applications

Stocked in multiple lengths and head styles. Order before 4:00pm CST and we’ll ship it out the same day for most orders.
