1/2 x 3-1/2 Hex Lag Screws - Galvanized Box/25

Overview

The 1/2 x 3-1/2 Hex Lag Screws - Galvanized Box/25 (05595) is designed for heavy-duty fastening applications including timber-to-timber connections and wood-to-masonry or concrete installations.

Technical Features

• 1/2" x 3-1/2" Dimensions: Large-diameter, full-length shank provides high clamping force and deep thread engagement for load-bearing connections.
• Hexagonal Head: Accepts standard wrench or socket drive, allowing high torque application without the risk of cam-out associated with slotted or Phillips drives.
• Galvanized Finish: Zinc galvanization provides a corrosion-resistant coating, making these screws suitable for outdoor, exposed, or moisture-prone environments.
• Lag Screw Design: Coarse, aggressive threading along the shank is engineered to grip wood fibers securely, resisting pull-out and shear forces under heavy loads.
• Box of 25: Sold in a job-site quantity, reducing per-unit cost for larger structural fastening projects.

Applications

• Fastening heavy timbers to one another in structural framing, decking, and post-and-beam construction.
• Securing wood members to masonry or concrete substrates when used with appropriate anchors or inserts.
• Outdoor and exposed structural assemblies where corrosion resistance is required due to galvanized finish.
• Dock, pergola, fence post, and heavy landscape structure installations requiring a reliable, load-rated mechanical connection.
