Description

3/8" x 3-1/2" Conquest Hex Head Lag Bolt for Wood - Hot Dip Galvanized

The 3/8" x 3-1/2" Conquest Lag Bolt provides extra depth and strength for fastening heavier outdoor wood assemblies. Hot dip galvanized for corrosion protection, it’s designed for secure long-term performance in decks, frames, and fence structures. Coarse threading cuts cleanly into dense or treated lumber.

3/8" x 3-1/2" Conquest Hex Head Lag Bolt – Galvanized Lag for Long Wood Connections

This bolt is built for joining thicker wood sections and adds strength in structural areas that face regular stress and exposure. Use it for mid-to-heavy-duty installs where length and corrosion resistance are critical.

Key Features

  • 3-1/2" Length: Longer reach for robust exterior fastening.
  • Hot Dip Galvanized: Shields against weather and moisture.
  • Hex Head: Works with common tools for quick install.
  • 7 TPI Coarse Threads: Ensures a tight, durable connection.

Common Applications

  • Deck posts and framing
  • Fence rail joints
  • Heavy garden structure frames
  • Wood platform framing
  • Outdoor cabinetry builds

Installation Tips

  • Drill full-depth pilot holes to reduce driving resistance.
  • Keep the driver aligned to prevent torque loss.
  • Check for flush fit to maintain structural integrity.

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!
