Description

5/8" x 3-1/2" Conquest Hex Head Lag Bolt for Wood - Hot Dip Galvanized

The 5/8" x 3-1/2" Conquest Lag Bolt is built for deeper anchoring in outdoor timber assemblies. Its hot dip galvanized coating provides long-term resistance to rust and environmental exposure, while coarse threading locks securely into pressure-treated or hardwood lumber.

5/8" x 3-1/2" Conquest Hex Head Lag Bolt – Galvanized Deep Bolt for Structural Wood Builds

This bolt is ideal for exterior frames, large wood joinery, or outdoor post-to-beam connections. Its extended reach offers increased grip where strength and longevity are critical.

Key Features

  • 3-1/2" Length: Offers more bite for thicker joints and frames.
  • Hot Dip Galvanized: Designed for durability in wet, humid, or treated environments.
  • Hex Head: Works with common power and hand tools.
  • 5 TPI Coarse Threads: Cuts deep for stable, anti-loosening grip.

Common Applications

  • Beam connections
  • Deck stair framing
  • Post-to-brace attachments
  • Garden structure frames
  • Outdoor utility buildings

Installation Tips

  • Drill a full-length pilot hole to reduce resistance.
  • Apply steady torque to avoid thread stripping.
  • Seat flush for maximum surface tension and hold.

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!
