3/8" x 3-1/4" 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

nuts and bolts

very good company to order bolts, nuts and washers from. even with shipping more than all the items l bought, it was many dollars lower than going to Lowes or Home Depot. will buy from again if l need fasteners. very good and quick service.
