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

Extreme Structural Anchoring
The heavy-duty 1/2 diameter combined with a 5-inch reach provides substantial shear resistance for large-scale timber projects. These fasteners are specifically designed for deep anchoring applications, such as securing 6x6 posts to structural headers and building robust retaining walls where maximum stability is required.

304 Stainless Corrosion Protection
Manufactured from premium 18-8 (304) stainless steel, offering effective resistance against rust in outdoor or humid environments. They are compatible with ACQ pressure-treated lumber, helping to maintain structural integrity and reduce the likelihood of rust staining on high-value wood surfaces like cedar and redwood.

Partial Thread Clamping Design
The partially threaded shank allows the bolt to pull the outer timber 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 thick connected timber 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 or very long wood, applying a small amount of lubricant to the threads is recommended. Use low-speed settings to avoid thread galling during high-torque application.
