1/4 x 1-1/2 Hex Lag Scrw HDG

Overview

The 1/4 x 1-1/2 Hex Lag Screw HDG (05556) is designed for heavy-duty wood-to-wood and wood-to-masonry fastening applications requiring corrosion-resistant hardware.

Technical Features

• Hot Dip Galvanized finish: Provides a thick, metallurgically bonded zinc coating that resists corrosion, making these fasteners suitable for outdoor and exposed environments.
• Hex head with 7/16 in. wrench requirement: Enables installation with a standard wrench or socket driver, delivering greater torque than slotted or Phillips-drive alternatives.
• Gimlet point: Self-starting tip penetrates wood fibers without pre-drilling in appropriate applications, reducing installation steps.
• Partial thread length: Unthreaded shank beneath the head draws mating materials tightly together, creating a secure clamping force between joined members.
• Steel construction: Provides the tensile and shear strength required for structural and heavy-load fastening tasks.
• 100-piece package quantity: Bulk packaging supports project-scale procurement and reduces per-unit cost on large installations.

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 anchoring inserts.
• Outdoor and exposed installations where galvanized corrosion resistance is required by code or project specification.
• General construction, landscaping, and utility applications requiring a large-format, wrench-driven wood fastener.
