IMSCREWS 5/16" x 1-1/2" Heavy-Duty Hex Head Lag Screws - 304 Stainless Steel (10 PCS)

Reliable Structural Mounting
The 5/16" diameter provides a balance of high shear strength and versatility for medium-to-heavy wood projects. These screws are suitable for mounting gate hardware, securing structural brackets, or attaching timber to 2x lumber (1.5" thickness) without the tip protruding through the back.

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 the integrity of your project when exposed to moisture and the elements.

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 suitable for high-tension mounting in shallow-depth applications where maximum grip is required.

FAQ
¡ñ Installation Tool: Use a standard 1/2" hex socket or wrench.
¡ñ Pre-drilling: To reduce the risk of timber splitting and ensure a smooth installation, pre-drilling a pilot hole is recommended (approx. 3/16" for softwoods or 7/32" for hardwoods).
¡ñ Application: Ideal for securing deck accessories, mounting mailboxes to posts, and general outdoor wood-to-wood or metal-to-wood fastening.
