IMSCREWS 1/2" x 3" Heavy-Duty Hex Head Lag Screws - 304 Stainless Steel (2 PCS)

Superior Structural Anchoring
The heavy-duty 1/2" diameter provides substantial shear resistance for structural timber projects. At 3 inches in length, these fasteners are suitable for securing structural brackets, mounting ledger boards, and connecting heavy lumber components where dependable stability is required.

304 Stainless Corrosion Protection
Manufactured from 18-8 (304) stainless steel, providing effective resistance against rust in outdoor or humid environments. Compatible with ACQ pressure-treated lumber, helping to maintain structural integrity and prevent rust staining on premium wood surfaces like cedar and redwood.

Partial Thread Clamping Design
The partially threaded shank allows the bolt to pull the outer timber board tightly against the support structure. This design facilitates a firm joint by ensuring the threads only engage the base material, helping to eliminate gaps between the connected surfaces.

FAQ
¡ñ Installation Tool: Use with a standard 3/4" hex socket or wrench.
¡ñ Pre-drilling Guide: To prevent timber splitting and ensure a secure fit, pre-drilling a pilot hole is required. Use a 5/16" bit for softwoods or an 11/32" bit for hardwoods.
¡ñ Installation Tip: For smoother installation in dense wood, applying a small amount of lubricant to the threads is recommended. Use low-speed settings to avoid thread galling during high-torque application.
