3/8" x 12" Conquest Hex Head Lag Bolt for Wood - Hot Dip Galvanized

The 3/8" x 12" Conquest Lag Bolt is engineered for the most demanding deep-fastening jobs in outdoor wood construction. Its long shaft and coarse threads provide superior anchoring, while the hot dip galvanized coating protects against rust and corrosion in high-moisture environments.

This bolt is perfect for large beam framing, outdoor structures, and layered timber assemblies where full-length anchoring is required. Built for long-term durability and professional-grade holding power.

Key Features

  • 12" Length: Maximum depth for thick wood assemblies and outdoor structures.
  • Hot Dip Galvanized: Delivers rust protection for years in harsh environments.
  • Hex Head: Installs smoothly with high-torque tools.
  • 7 TPI Coarse Threads: Ensures deep engagement and vibration resistance.

Common Applications

  • Timber frame joints
  • Bridge and pier anchoring
  • Deck or patio support systems
  • Long-span shelter construction
  • Retaining structure reinforcement

Installation Tips

  • Drill pilot holes the full bolt length to avoid thread damage.
  • Drive steadily to prevent bending or shifting.

Received on time!

Ordered these late, and under pressure, but received on time! Note that you need a 3/4 socket and it's not typical in most sets.
