Technical Features
- Hot-Dip Galvanized (HDG) Finish: Provides a thick, metallurgically bonded zinc coating that resists corrosion, making this fastener suitable for outdoor, treated lumber, and moisture-exposed applications.
- Hexagonal Head Design: Allows installation with a standard wrench or socket driver, enabling high-torque driving for secure seating in dense or heavy timber.
- 5/16 in. Diameter: Delivers substantial shear and withdrawal strength appropriate for structural and load-bearing connections.
- 2-1/2 in. Length: Provides sufficient thread engagement depth for reliable pull-out resistance in timber-to-timber and wood-to-masonry assemblies.
- Lag Screw Thread Form: Coarse, aggressive threading is designed to bite into wood fibers, maximizing holding power without the need for a nut or pre-installed insert.
Applications
- Fastening heavy timbers to one another in structural framing, decking, and beam construction.
- Anchoring wood members to masonry or concrete substrates where a pre-drilled pilot hole is used.
- Exterior and pressure-treated lumber applications where corrosion resistance is required.
- General heavy-duty wood construction where standard wood screws are insufficient for the load demands.
