1/2 x 5-1/2 Hex Lag Screws - Galvanized Box/25

Overview

The Midwest Fastener Corp. 1/2 x 5-1/2 Hex Lag Screws – Galvanized (05599) are designed for heavy-duty wood fastening applications including timber-to-timber connections and wood-to-masonry or concrete installations.

Technical Features

• Hexagonal head design: Accepts standard wrenches and socket drives, enabling high-torque installation for secure, load-bearing connections.
• 1/2" diameter shaft: Large fastener diameter distributes clamping force across a wider bearing area, suited for heavy structural loads.
• 5-1/2" length: Extended shank provides deep thread engagement into substrate material, increasing pull-out resistance in structural assemblies.
• Galvanized finish: Zinc coating provides corrosion resistance, extending service life in outdoor, exposed, or moisture-prone environments.
• Sold in a box of 25: Consistent batch quantity supports project planning and inventory management for contractors and builders.

Applications

• Fastening heavy timbers to one another in framing, decking, and structural carpentry.
• Securing wood members to masonry or concrete substrates where high withdrawal strength is required.
• Outdoor construction applications where galvanized corrosion resistance is necessary for long-term fastener integrity.
• General heavy-duty wood fastening where standard wood screws are insufficient due to load or material thickness.
