Description

3/4" x 3-1/2" 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 3/4" diameter Conquest A307 Grade A Hex Bolts are built from carbon steel and designed for reliable structural fastening in outdoor and high-moisture conditions. The hot dip galvanized finish provides excellent corrosion resistance, while the coarse thread profile delivers a strong grip and easy installation using standard SAE tools.

3/4" HDG Hex Bolts for Framing, Anchoring, and Outdoor Builds

Meeting ASTM A307 Grade A specifications, these bolts are a top choice for general-purpose use in residential, commercial, and agricultural construction. Whether anchoring wood to concrete, assembling structural frames, or building outdoor pavilions, these bolts deliver consistent strength and long-lasting performance.

Key Features

  • 3/4" Diameter Carbon Steel: Built for medium-duty structural fastening in outdoor environments.
  • Hot Dip Galvanized Finish: Provides long-term rust and weather resistance for exposed applications.
  • ASTM A307 Grade A Compliant: Manufactured to meet general structural and construction standards.
  • Standard SAE Measuring System: Compatible with U.S. spec tools and sizing requirements.
  • Coarse Thread Profile: Ensures secure grip and fast threading into wood or metal surfaces.
  • Hex Head Design: Easy to tighten or remove using standard wrenches or socket tools.
  • Outdoor Application Ready: Ideal for deck framing, fencing, pergolas, and agricultural buildings.

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!

Home Improvements

My husband are Do it ourselves kind of people and we built a pergola, but needed longer
bolts that cannot be found in most Hardware stores. Searched around and found Fasteners Plus and received our order in 3 days. Thank you so much.
