"IMSCREWS 5/16 x 4 Heavy-Duty Lag Screws - 304 Stainless Steel (5 pcs)
Extreme Penetration for Structural Timber Our 4-inch lag bolts are engineered for projects requiring maximum reach and anchoring depth. The robust 5/16 diameter provides professional-grade shear resistance, making these ideal for securing thick timber beams, landscape timbers, or structural components to 4x4 and 6x6 posts.
Vise-Like Clamping Power Our partially threaded shank features a smooth upper section that allows the bolt to pull the outer timber tightly against the support beam. This creates a gap-free, rock-solid joint, eliminating the bridging effect common in extra-long full-thread screws for a professional-grade finish.
304 Stainless Protection Forged from premium 18-8 (304) stainless steel for elite rust protection in outdoor and humid environments. compatible with ACQ pressure-treated lumber. Prevents unsightly rust streaks on high-value cedar, redwood, or premium deck framing.
FAQ ¡ñ Tools: Fits a standard 1/2 hex socket or wrench. ¡ñ Pre-drilling: Mandatory for this length. Use a 3/16 bit for softwoods or 7/32 for hardwoods to prevent timber splitting. ¡ñ Why 4 length? Perfect for passing through 2 or 2.5 thick timber with a deep 1.5 + thread anchor in the base beam.
DEEP-ANCHOR CLAMPING The 4 length with a partial thread allows the shank to bypass the outer board, pulling timbers together for a gap-free, rock-solid joint.
STRUCTURAL SHEAR STRENGTH At 5/16 diameter, these bolts provide professional-grade lateral resistance for high-load beam and post connections.
304 EXTERIOR DEFENSE Forged from 304 (18-8) stainless steel to prevent rust and corrosive staining in cedar, redwood, or ACQ pressure-treated lumber.
HIGH-TORQUE PERFORMANCE Robust hex head ensures a secure 1/2 socket fit, providing maximum torque transfer for controlled installation in dense hardwoods.
TECHNICAL SPECIFICATION To ensure structural safety and prevent splitting, pre-drilling a pilot hole (7/32 for softwoods, 1/4 for hardwoods) is mandatory.
