Description

When pairing a nut with a hex bolt, the material and finish must match. If these do not match, the nut will not fit the bolt.

Conquest A307 Grade A Hex Bolts with Hot Dip Galvanized finish are engineered for strength, reliability, and corrosion resistance in tough construction environments. Designed for securing wood or metal components in structural and general-purpose projects, these hex bolts meet ASTM A307 Grade A standards — making them an ideal fastening choice for builders, contractors, and serious DIYers.

Each bolt features a durable 6" threaded section and coarse threading that provides excellent grip in a variety of substrates. The hot dip galvanized coating ensures long-lasting protection against rust and harsh outdoor elements — perfect for use in decks, post-frame buildings, infrastructure, and other exterior applications.

Whether you’re anchoring heavy timber or assembling structural steel components, these hex bolts deliver strength you can count on.

Features:

  • ASTM A307 Grade A Steel: Built from low carbon steel to meet standard structural requirements.
  • 6" Thread Length: Offers deep, secure engagement in various materials.
  • Hot Dip Galvanized Coating: Provides superior corrosion resistance for exterior and high-moisture environments.
  • Multiple Size Options: Available in a variety of diameters and lengths to suit your build.
  • Versatile Construction Use: Ideal for commercial, residential, and agricultural projects.

Porch rail

I built porch rail like 15 years ago, the top rail was starting to warp upwards, so a long bolt was needed. Product did the job. However shipping was a bit high. But I needed product.

Great customer service !

I placed an order for oversized hardware and it shipped right away. Unfortunately UPS lost part of the order with no tracking updates for a few days. I called and DeAnna shipped out replacements immediately, so as not to delay my project. Top product, great price, top service !
