3/8" x 4-1/2" Conquest A307 Grade A Hex Bolt - Hot Dip Galvanized

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.

These 3/8" diameter Conquest A307 Grade A Hex Bolts are built from carbon steel and hot dip galvanized to withstand harsh outdoor conditions. With coarse threads and a hex head design, they’re ideal for wood-to-wood or wood-to-steel fastening in residential, commercial, and agricultural construction.

General-purpose structural fastening for High-Moisture and Outdoor Environments

Engineered to ASTM A307 Grade A specifications, these general-purpose bolts provide dependable tensile strength for framing, equipment anchoring, and structural assembly. The corrosion-resistant coating ensures long-term performance in decks, fencing, post-frame buildings, and more.

Key Features

  • 3/8" Diameter Carbon Steel: Delivers reliable strength for light to moderate structural applications.
  • Hot Dip Galvanized Finish: Protects against rust and moisture in outdoor environments.
  • ASTM A307 Grade A Compliant: Meets construction standards for non-critical structural fastening.
  • Coarse Thread Profile: Ensures strong grip in wood, concrete (with anchors), and steel connections.
  • Hex Head Design: Compatible with standard wrenches or sockets for fast, efficient installation.
  • Versatile Applications: Ideal for decks, pergolas, equipment mounting, and agricultural structures.
  • Available in Multiple Sizes: Wide selection of diameters and lengths for job-specific needs.

Common Applications

  • Outdoor decking and fencing installations
  • Wood-to-metal fastening for agricultural or utility structures
  • General construction in high-moisture environments
  • Repair and maintenance of outdoor wooden frameworks
  • Clamping multi-layer assemblies requiring full thread engagement

Installation Tips

  • Always pair with hot dip galvanized nuts and washers to maintain corrosion resistance and thread compatibility
  • Tighten bolts evenly across their full length to prevent misalignment or overtightening in softer materials
  • Inspect for coating buildup and clean threads if needed before installation for a smooth fit

Great Product Selection, Even Better Service and Ship Speed

Love the selection of bolts, nuts, and all other related hardware at this place! You can find most everything here. The low Fastener part(s) prices usually offset the shipping costs with any volume of parts at all.... and that selection, very good. Shipping was incredibly fast and the call I had with their support yielded "above and beyond" support that I needed and really appreciated.
