5/8" x 18" Conquest Hex Head Lag Bolt for Wood - Hot Dip Galvanized

The 5/8" x 18" Conquest Lag Bolt offers deep-penetration strength and rugged corrosion protection for extreme outdoor builds. Its coarse 5 TPI threads provide strong wood engagement, and the hot dip galvanized finish shields it from the harshest environments.

5/8" x 18" Conquest Hex Head Lag Bolt – Galvanized Extra-Long Bolt for Maximum Timber Fastening

Use this bolt for oversized timber assemblies, retaining structures, or any application that demands maximum holding strength in treated or weather-exposed wood.

Key Features

  • 18" Length: Ideal for large wood framing and anchoring.
  • Hot Dip Galvanized: Resists corrosion from moisture, salt, and treatment chemicals.
  • Hex Head: Installs with high-torque tools easily and quickly.
  • 5 TPI Threads: Cuts fast and holds firm under stress.

Common Applications

  • Oversized structural timber framing
  • Massive deck or dock supports
  • Bridge and boardwalk frames
  • Large retaining wall ties
  • Outdoor shelter foundations

Installation Tips

  • Use a long drill bit for full-depth pilot hole creation.
  • Apply even pressure during driving to prevent bending.
  • Ensure bolt is seated flush for best load transfer and safety.

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!
