IMSCREWS 1/2 x 4 Heavy-Duty Hex Head Lag Screws - 304 Stainless Steel (1 PCS)

Reliable Structural Anchoring
The 1/2 diameter provides substantial shear resistance for structural timber projects. At 4 inches in length, these fasteners are suitable for securing ledger boards, deck posts, and heavy framing 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 reduce the likelihood of rust staining on premium wood surfaces.

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

FAQ
¡ñ Installation Tool: Use with a standard 3/4 hex socket or wrench.
¡ñ Pre-drilling Guide: To prevent timber splitting, pre-drilling a pilot hole is required. Use a 5/16 bit for softwoods or an 11/32 bit for hardwoods to ensure a secure fit without over-stressing the bolt during installation.
¡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.
