IMSCREWS 1/2" x 5" Heavy-Duty Hex Head Lag Screws - 304 Stainless Steel (5 PCS)

High-Load Structural Connection
Engineered with a 1/2" diameter to provide substantial shear resistance for large-scale timber projects. These fasteners are suitable for securing heavy beams, anchoring structural posts, and supporting outdoor building components that require reliable load-bearing capacity.

304 Stainless Corrosion Protection
Manufactured from 18-8 (304) stainless steel, providing effective resistance against rust in outdoor, humid, or coastal environments. Compatible with ACQ pressure-treated lumber, helping to maintain structural integrity when exposed to the elements.

Partial Thread Clamping Design
The partially threaded shank allows the bolt to pull the outer board tightly against the support structure. This design helps reduce gaps between timber surfaces, facilitating a firm joint that fully threaded screws may not achieve at this length.

FAQ
¡ñ Installation Tool: Use a standard 3/4" hex socket or wrench.
¡ñ Pre-drilling: To reduce the risk of timber splitting, pre-drilling a pilot hole is recommended (approx. 5/16" for softwoods or 3/8" for hardwoods).
¡ñ Application: Ideal for deck beam-to-post connections, pergola framing, and heavy landscape timber.

Key Features

• [STAIR STRINGER SPECIALIST] The 5-inch length is dimensioned for securing heavy-duty stair stringers to deck frames. This 5-pack provides the structural anchoring power required for safe residential stair installation.
• [OPTIMIZED DRAW-DOWN DESIGN] Engineered with a 3.2" partial thread and 1.8" smooth upper shank. This ratio ensures the shank clears standard 2x lumber, allowing the threads to pull the timbers together for a gap-free bond.
• [HEAVY-DUTY SHEAR STRENGTH] The robust 1/2-inch diameter provides the necessary shear resistance for primary load-bearing connections where standard wood screws lack the structural capacity.
• [304 STAINLESS PROTECTION] Manufactured from 304 (18-8) stainless steel for outdoor durability. Resistant to oxidation in high-moisture environments and compatible with ACQ pressure-treated lumber.
• [INSTALLATION SPECIFICATIONS] Drive with a 3/4" hex socket. To prevent timber splitting and ensure structural integrity, pre-drilling a pilot hole (11/32" for softwoods, 3/8" for hardwoods) is required.
