"IMSCREWS 5/16 x 1 Heavy-Duty Lag Screws - 304 Stainless Steel (20 pcs)

Maximum Strength for Compact Fastening
When 1/4 screws aren't enough, these 5/16 thick fasteners provide superior shear resistance. Optimized for mounting heavy-duty hardware, steel brackets, or gate latches to standard lumber where depth is limited. The 1-inch length is perfect for high-strength anchoring without piercing through the back of the timber.

Fully Threaded for Maximum Grip
Features a fully threaded design to ensure constant engagement from the tip to the head. This maximizes surface area contact in shallow depths, providing superior pull-out resistance and immediate bite in both softwoods and hardwoods.

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

FAQ
• Tools: Fits a standard 1/2 hex socket or wrench.
• Pre-drilling: Recommended. Use a 3/16 bit for softwoods or 7/32 bit for hardwoods to prevent splitting.
• Why this size? Provides a much higher load capacity than standard screws for heavy-duty hardware mounting in 1.5 boards.
