5/8" x 20" Conquest Hex Head Lag Bolt for Wood - Hot Dip Galvanized

The 5/8" x 20" Conquest Lag Bolt is one of the longest outdoor-grade bolts available, built to secure massive timber assemblies under the harshest outdoor conditions. The coarse threading bites deep, while the hot dip galvanized finish protects for the long haul.

This bolt is the go-to choice when deep, high-load fastening is needed for structural beams, retaining walls, or timber frameworks exposed to the elements.

Key Features

  • Hot Dip Galvanized: Superior corrosion defense for all-weather builds.
  • Hex Head: Standard size for easy installation with power tools.
  • 5 TPI Threads: Ensures lasting grip and anti-loosening security.

Common Applications

  • Structural framing in large outdoor buildings
  • Deep beam-to-post anchoring
  • Heavy timber retaining systems
  • Bridge and platform reinforcement
  • Oversized fencing and framing assemblies

Installation Tips

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!
