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

This 1/2" x 3-1/2" Conquest Lag Bolt offers deeper penetration for larger-scale wood fastening. The hot dip galvanized finish shields it from outdoor wear, including rain, soil exposure, and treated wood chemicals. Its coarse thread profile ensures strong grip and reliable holding power in any exterior application.

1/2" x 3-1/2" Conquest Hex Head Lag Bolt – Galvanized Lag Screw for Heavy Wood

Use this bolt for securing beams, posts, or thick framing elements outdoors. It’s made to perform where rust or bolt failure would compromise the job. Built strong, easy to install, and tough enough for high-exposure applications.

Key Features

  • 3-1/2" Length: Ideal for large outdoor wood connections.
  • Hot Dip Galvanized: Designed to withstand the elements and protect against rust.
  • Hex Head: Provides torque control during installation.
  • 6 TPI Coarse Threads: Locks into wood for high-load strength.

Common Applications

  • Heavy outdoor framing
  • Deck and stair structures
  • Post and beam fastenings
  • Fence or gate bracing
  • Exposed wood installations

Installation Tips

  • Drill a pilot hole to reduce wood stress and improve alignment.
  • Use impact tools for easier driving into thick lumber.

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!
