HILLMAN 1/2 in. X 12 in. L Hex Hot Dipped Galvanized Steel Lag Screw 25 pk

Meet the Hillman 1/2 in x 12 in Hex Lag Screw, a heavy-duty fastening solution engineered for outdoor timber projects. Each 25-pack is crafted from steel and finished with hot-dipped galvanizing for lasting corrosion resistance in rain, humidity, or coastal air.

Key features:

• Size and strength: 1/2" diameter by 12" length provides deep bite and excellent withdrawal resistance for framing, decking, and heavy timber connections.
• Hex head design: Hex head accepts common wrenches or socket drivers for secure, high-torque driving without cam-out.
• Coarse thread: Optimized for wood-to-wood fastening, delivering a strong hold with fewer passes through the material.
• Coating for outdoor durability: Hot-dipped galvanized finish shields against rust and corrosion, extending the life of outdoor structures in wet or salty environments.
• Package: 25-count box for job-site convenience and restocking.

Best uses:

• Decks, fences, pergolas, and garden structures—especially in damp or coastal climates where moisture challenges are common.
• Timber framing and heavy-duty wood connections where a longer, stout fastener is required.
• Pre-drilling and pilot hole guidance: start with a pilot hole sized to the screw’s core diameter to reduce splitting and ensure straight driving; for hardwoods, consider a slightly larger pilot.

Why this matters:

• The combination of 1/2" diameter and 12" length delivers robust hold in thick timber, reducing movement and increasing structural integrity over time.
• Galvanized coating minimizes rust streaks and preserves aesthetics and strength in outdoor installations.
• Hex head + coarse thread translates to faster, more reliable installation on-site, even when you're wearing gloves or working with bulky lumber.
