Technical Features

  • Heat-treated and hardened construction: Increases structural integrity and durability over standard untreated screws, reducing the risk of shear or breakage under load.
  • Triple-coated bronze finish: Provides high corrosion resistance, extending service life in exposed or chemically treated lumber environments.
  • ACQ certified: Approved for use with Alkaline Copper Quaternary (ACQ) pressure-treated lumber, ensuring compatibility with modern treated wood without accelerated corrosion.
  • Deep-cutting threads: Engineered for quick and efficient driving, reducing installation time and driver wear in dense or engineered lumber.
  • Sharp point tip: Enables fast starting without pre-drilling, improving installation speed on the job site.
  • T-40 drive interface: Provides high torque transfer and reduced cam-out compared to standard Phillips or slotted drives, supporting consistent driving in heavy structural applications.
  • 100-count mini carton packaging: Offers manageable quantities for project staging and on-site organization.

Applications

  • Structural framing and heavy timber connections requiring high holding strength
  • Decking, fencing, and outdoor construction using ACQ or other pressure-treated lumber
  • Ledger board and beam attachments where corrosion resistance is critical
  • Any application where standard lag screws are insufficient due to chemical treatment exposure or moisture
