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

Professional Grade Structural Strength
Engineered for heavy-duty timber connections, the 5/16 diameter provides significantly higher shear resistance than standard 1/4 screws. The 2-inch length is ideal for securing thick metal brackets, deck railings, or mounting hardware to 4x posts and beams.

Vise-Like Clamping Power
Our partially threaded shank features a smooth upper section that allows the bolt to pull the outer board or hardware tightly against the support post. This creates a gap-free, rock-solid joint, preventing the bridging effect common in long full-thread screws for a professional finish.

304 Stainless Exterior Defense
Forged from premium 18-8 (304) stainless steel for elite rust protection in outdoor environments. compatible with ACQ pressure-treated lumber. Prevents unsightly corrosion streaks on high-value cedar, redwood, or premium deck framing.
