"IMSCREWS 1/4 x 3 Heavy-Duty Lag Screws - 304 Stainless Steel (10 pcs)

Extended Reach for Structural Framing
When projects demand deep penetration, these 3-inch bolts deliver. Engineered for securing double-layered lumber, mounting heavy fence rails, or attaching deck components to 4x posts. The 1/4 diameter provides high shear resistance for safety-critical joints.

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

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

FAQ
• Tools: Fits a standard 7/16 hex socket or wrench.
• Pre-drilling: Recommended. Use a 1/8 bit for softwoods or 3/16 for hardwoods to prevent splitting.
• Why 3 length? Perfect for passing through 1.5 timber with a deep 1.5 thread anchor in the base post.

Key Features

  • ULTIMATE CLAMPING POWER The engineered partial thread allows the smooth shank to bypass the outer board, pulling timber members together for a rock-solid, gap-free joint.
  • DEEP-CORE ANCHORING At 3 inches long, these bolts provide the perfect structural depth for connecting 2x4 lumber to support posts with maximum withdrawal resistance.
  • 304 EXTERIOR DEFENSE Forged from premium 304 (18-8) stainless steel to prevent rust and staining in cedar, redwood, or ACQ pressure-treated lumber.
  • STABLE TORQUE INTERFACEPrecision hex head ensures a secure 7/16 socket fit, offering stable torque transfer for controlled seating in dense structural timber.
  • TECHNICAL SPECIFICATION To prevent splitting and protect the 1/4 shaft, pre-drilling a pilot hole (3/16 for softwoods, 7/32 for hardwoods) is mandatory.
