"IMSCREWS 5/16 x 2 Heavy-Duty Lag Screws - 304 Stainless Steel (10 pcs)

The Structural Standard for Outdoor Framing
An essential fastener for medium-duty structural projects. The 2-inch length provides deep penetration into 4x4 posts while the 5/16 diameter offers superior shear resistance compared to 1/4 alternatives. Ideal for securing gate hinges, deck railing posts, and heavy-duty shelving brackets.

Vise-Like Clamping with Partial Threading
Our partially threaded shank features a smooth upper section that allows the bolt to spin freely in the outer board. This draws the timber members together into a gap-free, rock-solid joint, eliminating the bridging effect where boards remain loose—a critical feature for ensuring structural integrity in outdoor wood projects.

304 Stainless Exterior Defense
Forged from premium 18-8 (304) Stainless Steel for ultimate weather protection. compatible with ACQ pressure-treated lumber, preventing chemical corrosion and unsightly rust streaks on high-value cedar, redwood, or deck framing.
