5/16" x 6" Conquest A307 Grade A Hex Bolt with Hot Dip Galvanized Finish

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 5/16" diameter Conquest A307 Grade A Hex Bolts are engineered for dependable fastening in outdoor construction, framing, and structural assemblies. Hot dip galvanized for corrosion protection and built from carbon steel, they deliver reliable strength for residential, commercial, and agricultural projects.

Built for Durability in High-Moisture and Exterior Environments

With a coarse thread profile and 18 threads per inch, these bolts provide strong engagement in wood and mild steel. Designed to ASTM A307 Grade A standards and using the Standard SAE measuring system, they are ideal for wood-to-wood, wood-to-metal, and structural steel applications where corrosion resistance and consistency are key.

Key Features

  • 5/16" Diameter Carbon Steel: Suitable for light structural and outdoor general-purpose fastening.
  • Hot Dip Galvanized Finish: Resists rust and corrosion in high-moisture and outdoor settings.
  • 18 TPI Coarse Threads: Offers reliable grip and strong fastening performance.
  • ASTM A307 Grade A Compliant: Built to recognized construction and structural standards.
  • Standard SAE Measuring System: Compatible with standard construction specs and tooling.
  • Hex Head Design: Easily installed using common wrenches or socket tools.
  • Field-Ready Applications: Ideal for decking, framing, fencing, and post anchoring jobs.

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

Overall experience

The bolts are great. This review is about my overall experience working with Fasteners Plus. I needed to make a change in my order and this company went way above and beyond to accommodate me. It was going to be more expensive to return some hardware that I ordered by mistake and they simply sent the correct hardware and told me to keep the bolts I ordered in error. Great to work with!
