IMSCREWS 1/2 x 1-1/2 Heavy-Duty Hex Head Lag Screws - 304 Stainless Steel (10 PCS)

Robust Structural Mounting
The heavy-duty 1/2 diameter provides substantial shear resistance for critical structural wood projects. At 1.5 inches in length, these fasteners are specifically designed for mounting post bases, heavy-duty joist hangers, and thick metal brackets to standard 2x lumber where maximum stability is required without the tip protruding through the opposite side

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

Full-Thread Maximum Engagement
Featuring a fully threaded design, these bolts ensure extensive engagement with wood fibers from the tip to the head. This provides strong pull-out resistance, making them ideal for high-load mounting in shallow-depth applications where maximum thread grip is essential for safety

FAQ
¡ñ Installation Tool: Use with a standard 3/4 hex socket or wrench
¡ñ Pre-drilling Guide: To prevent timber splitting and ensure smooth installation, pre-drilling a pilot hole is required. Use a 5/16 bit for softwoods or a 3/8 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

Key Features

• [MAXIMUM THREAD ENGAGEMENT] Engineered with a fully threaded profile to ensure grip from the tip to the hex head. Ideal for shallow 1-1/2 inch applications where every millimeter must bite into the wood for withdrawal resistance.
• [HEAVY-DUTY SHEAR CAPACITY] The robust 1/2-inch diameter offers professional-grade shear resistance. Designed for securing heavy metal brackets, post bases, and dock hardware where standard screws lack structural integrity.
• [304 STAINLESS CORROSION DEFENSE] Forged from 304 (18-8) stainless steel to prevent rust and oxidation. Chemically compatible with ACQ pressure-treated lumber for long-term outdoor durability.
• [COMPACT STRUCTURAL ANCHOR] The 1-1/2 inch length provides powerful anchoring without over-penetrating the timber. Suitable for heavy-duty hinges and structural connectors on standard framing lumber.
• [INSTALLATION SPECIFICATIONS] Drive with a 3/4" hex socket. To prevent timber splitting, pre-drilling a pilot hole (11/32" for softwoods, 3/8" for hardwoods) is required.
