3/8 x 5 Hex Lag Screws - Galvanized Box/50

Overview

The 3/8 x 5 Hex Lag Screws - Galvanized Box/50 (05585) is designed for heavy-duty fastening applications including securing heavy timbers together and anchoring wood to masonry or concrete substrates.

Technical Features

• Hexagonal head design: Accepts a wrench or socket drive, enabling high-torque installation suited for heavy structural connections.
• 3/8 in. diameter x 5 in. length: Large fastener profile provides deep embedment and substantial holding strength in timber and masonry applications.
• Galvanized finish: Zinc galvanization provides corrosion resistance, making these screws suitable for outdoor, exposed, or moisture-prone environments.
• Lag screw thread form: Coarse threading is engineered to bite aggressively into wood fibers, resisting pull-out under heavy loads.
• Box of 50: Bulk packaging supports project-quantity purchasing, reducing per-unit cost for multi-fastener structural jobs.

Applications

• Fastening heavy timbers to one another in structural framing, decking, and timber construction.
• Anchoring wood members to masonry or concrete — including ledger board attachment and post base connections.
• Outdoor structural assemblies where galvanized corrosion resistance is required by code or environmental conditions.
• General heavy-duty wood-to-wood connections requiring a mechanically driven, high-retention fastener.
