1/2 x 10 Hex Lag Screws - Galvanized Box/25

Overview

The 1/2 x 10 Hex Lag Screws - Galvanized Box/25 (05603) is designed for heavy-duty fastening applications in construction, timber framing, and masonry anchoring. Manufactured by Midwest Fastener, this box of 25 galvanized hex lag screws provides a reliable fastening solution where structural integrity and corrosion resistance are required.

Technical Features

• Hexagonal head design: Allows for wrench or socket-driven installation, enabling high torque application for deep seating into dense timber or masonry substrates.
• Large-format dimensions (1/2" x 10"): Provides extended thread engagement and shank length suited for fastening thick or heavy structural members.
• Galvanized finish: Offers corrosion resistance, making these screws suitable for use in outdoor, exposed, or moisture-prone environments.
• Lag screw thread pattern: Features coarse threading similar to a wood screw but scaled for heavy-load applications, ensuring a firm mechanical grip in wood and compatible masonry anchors.
• Box quantity of 25 pieces: Packaged for job-site use, supporting multi-fastener structural assemblies without the need for multiple procurement orders.

Applications

• Securing heavy timber-to-timber connections in framing, decking, and structural assemblies.
• Fastening wood members to masonry or concrete substrates when used with appropriate anchor inserts.
• Outdoor construction projects where galvanized corrosion resistance is required for long-term fastener integrity.
• Ledger board attachment, post anchoring, and other load-bearing connection points in residential and commercial construction.
