IMSCREWS 5/16 x 1-1/4 Hex Head Lag Screws, 304 Stainless Steel 18-8, Fully Threaded, Pack of 10 - Heavy Duty Wood Screws

"IMSCREWS 5/16"" x 1-1/4"" Heavy-Duty Hex Head Lag Screws - 304 Stainless Steel (10 PCS)

Versatile Structural Mounting
The 5/16"" diameter provides a balance of shear strength and versatility for medium-to-heavy wood projects. At 1.25 inches in length, these fasteners are suitable for mounting hardware, securing gate hinges, or attaching lumber to standard boards where a clean finish is required without the tip protruding through the wood.

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 suitable for high-vibration or high-tension mounting in shallow-depth applications where maximum grip is essential.

FAQ
• Installation Tool: Use with a standard 1/2"" hex socket or wrench.
• Pre-drilling Guide: To prevent timber splitting and ensure smooth installation, pre-drilling a pilot hole is required. Use a 5/32"" bit for softwoods or a 7/32"" bit for hardwoods.
• 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.
