1/2 x 6 Hex Lag Screws - Galvanized Box/25

Overview

The 1/2 x 6 Hex Lag Screws - Galvanized Box/25 (05600) is designed for heavy-duty structural fastening applications including timber-to-timber connections and wood-to-masonry or concrete installations.

Technical Features

• 1/2" x 6" heavy-gauge shank: Large diameter and length provide the bearing surface required to securely fasten heavy timber assemblies under sustained structural load.
• Hexagonal head design: Engineered for wrench or socket-drive installation, enabling high torque application without tool slippage — critical for driving large-diameter fasteners into dense timber or masonry substrates.
• Galvanized finish: Zinc-coated surface provides corrosion resistance, making these screws suitable for outdoor, exposed, or moisture-prone environments where bare steel fasteners would degrade prematurely.
• Wood-screw thread profile: Coarse threading pattern, consistent with lag screw geometry, is optimized for maximum pull-out resistance in wood and wood-to-masonry connections.
• Box of 25 units: Packaged in project-ready quantities to support structural framing, deck construction, and similar multi-fastener applications without excess inventory.

Applications

• Timber-to-timber structural connections such as post-and-beam framing and heavy lumber assemblies
• Fastening dimensional lumber or heavy timbers to masonry or concrete foundations and walls
• Deck ledger board attachment to structural framing or masonry
• Outdoor structural assemblies where corrosion resistance is required due to weather exposure
• General heavy-duty construction requiring a high-strength, wrench-driven fastener solution
