"IMSCREWS 3/8 x 6 Extreme-Duty Lag Bolts - 304 Stainless Steel (5 pcs)

Ultimate Reach for Massive Timber
Industrial power for the thickest wood members. Engineered for 6x6 posts, retaining walls, and heavy marine docks. The 6-inch length provides elite stability for safety-critical load-bearing connections.

Vise-Like Clamping Power
Our partially threaded shank allows the bolt to pull the outer timber tightly against the support beam. This eliminates the bridging effect where thick boards remain loose, ensuring a gap-free, rock-solid joint that full-thread screws cannot achieve at this depth.

304 Stainless Protection
Premium 18-8 stainless steel resists rust in humid or coastal areas. compatible with ACQ pressure-treated lumber. Prevents unsightly rust streaks on cedar, redwood, or deck framing.

FAQ

¡ñ Why 6 length? Designed to pass through 3.5 or 4 timber with a deep 2 thread anchor.
¡ñ Resilience: Marine and coastal environment ready.

Key Features

  • ULTIMATE CLAMPING POWER The partially threaded design ensures the smooth shank bypasses the outer timber, pulling members together for a rock-solid, gap-free joint.
  • HEAVY-DUTY SHEAR STRENGTH The robust 3/8-inch diameter provides industrial-grade lateral load resistance, outperforming thinner fasteners for deck beams and pergolas.
  • 304 DEEP-CORE PROTECTION Forged from 304 (18-8) stainless steel to prevent rust and deep-seated rot in cedar, redwood, or ACQ pressure-treated lumber projects.
  • INDUSTRIAL DRIVE INTERFACE Precision hex head ensures a secure 9/16 socket fit, offering stable torque transfer for controlled seating in extra-thick timber.
  • TECHNICAL SPECIFICATION To prevent splitting from this robust 3/8 bolt, pre-drilling a pilot hole (1/4 for softwoods, 9/32 for hardwoods) is mandatory for structural integrity.
