Technical Features
- 1/2" diameter x 12" length: Large fastener dimensions provide the clamping force and thread engagement required for heavy structural timber connections.
- Hexagonal head design: Accepts a standard socket wrench or adjustable wrench, enabling high-torque installation without driver cam-out.
- Galvanized finish: Zinc galvanization provides a corrosion-resistant coating, making these lag screws suitable for outdoor and moisture-exposed installations.
- Lag screw thread form: Coarse, tapered threading is engineered to bite deeply into wood fiber, maximizing pull-out resistance in timber-to-timber and timber-to-masonry assemblies.
- Box quantity of 25: Packaged in a multi-unit box to support project-scale procurement and reduce per-fastener cost on larger jobs.
Applications
- Securing heavy structural timbers to one another in framing, decking, and post construction.
- Fastening wood ledgers, beams, or sill plates to masonry or concrete substrates.
- Deck and pergola construction where large-diameter, corrosion-resistant fasteners are required.
- Landscape timber retaining walls and outdoor structural assemblies exposed to weather.
