Product Details

  • Hot Dip Galvanized Hex Head Lag Screws, Heavy Duty Lag Bolts for Wood, TV Mounts, Deck, Boat Repair
  • Curated Premium Materials: These heavy-duty 3/8 bolts are crafted from high-grade alloy steel, boasting far superior mechanical properties than standard screws. The surface is treated with a hot-dip galvanizing process, creating a dual physical-electrochemical anti-rust barrier with self-healing capability. Its rust resistance and durability outperform conventional anti-corrosion solutions by a mile.
  • Professionally Engineered: The classic hex head design delivers exceptional torque capacity, effectively preventing stripping during installation — a key advantage over a standard wood screw. The self-drilling cutting slots at the tip drastically boost wood penetration efficiency, ensuring a smooth and effortless driving experience. Pro Tip: Skip pilot holes when using a high-power drill; for everyday use, pre-drilling a pilot hole is recommended for optimal fastening results.
  • Out-of-the-Box Ready: Each set includes 50 hot-dip galvanized hex head heavy-duty lag bolts and 50 premium alloy flat washers with precisely matched dimensions for maximum fastening stability. A free 14mm socket wrench is included — no extra tool purchases needed.
  • Multi-Scene Compatible: Designed exclusively for wood fastening, these lag screws are ideal for outdoor, household, and industrial applications — deck building, lumber joining, TV mount installation, yard light fixing, outdoor furniture repair, and boat railing reinforcement.
