1/2" x 20" Conquest Hex Head Lag Bolt for Wood - Hot Dip Galvanized

The 1/2" x 20" Conquest Lag Bolt is the ultimate solution for deep, load-bearing wood fastenings in outdoor or marine construction. Hot dip galvanized and built for performance, it withstands the harshest conditions while delivering superior strength. Its extra length ensures reach and retention across the thickest wood builds.

1/2" x 20" Conquest Hex Head Lag Bolt – Galvanized Lag Screw for Long-Distance Anchoring

Whether you're building piers, boardwalks, or structural supports, this lag bolt is made for extended penetration and enduring hold. With coarse threads and a strong hex head, it installs easily and performs reliably under pressure.

Key Features

  • 20" Length: Longest standard bolt for ultra-deep connections.
  • Hot Dip Galvanized: Maximum corrosion protection for outdoor jobs.
  • Hex Head: Simplifies installation with high-torque tools.
  • 6 TPI Coarse Threads: Engages fully in multi-board or beam setups.

Common Applications

  • Deep marine anchoring
  • Massive timber support structures
  • Piling or dock reinforcement
  • Bridge or outdoor infrastructure
  • Large-scale wood construction

Installation Tips

  • Drill pilot holes at matching depth to ease driving force.
  • Use high-torque equipment to handle bolt length and resistance.
  • Verify full seating and alignment before load is applied.

Great Purchase will buy again!

Our Production had literally come to a complete halt, because we were out of these and (surprise) our vendor was too!!!
We were extremely fortunate to have found you and the wealthy inventory you have!! We are excited to now have your company as our new and only provider of these fasteners!
