"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 ¡ñ Tools: Fits a standard 1/2 hex socket or wrench. ¡ñ Pre-drilling: Recommended. Use a 3/16 bit for softwoods or 7/32 bit for hardwoods to prevent splitting. ¡ñ Why this size? Provides a much higher load capacity than standard screws for heavy-duty hardware mounting in 1.5 boards.
SUPERIOR SHEAR RESISTANCE The oversized 5/16 diameter provides professional-grade lateral strength, preventing bending or snapping when securing heavy hardware.
MAXIMUM THREAD GRIP Fully threaded geometry maximizes wood fiber engagement within a 1-inch depth, ensuring rock-solid anchoring in shallow timber.
304 EXTERIOR STABILITY Forged from premium 304 (18-8) stainless steel to inhibit corrosion and rust bleeding in high-moisture outdoor environments.
HIGH-TORQUE INTERFACE Precision hex head provides a secure 1/2 socket fit, allowing for maximum torque transfer without the stripping common in Phillips screws.
TECHNICAL SPECIFICATION To prevent timber splitting and ensure precise fit, pre-drilling a pilot hole (7/32 for softwoods, 1/4 for hardwoods) is recommended.
