Description

1/4" x 1/2" Conquest A307 Grade A Fully Coarse Threaded 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.

Conquest A307 Grade A Fully Threaded Hex Bolts are built for general-purpose structural fastening where grip and corrosion resistance are key. Made from low carbon steel and hot dip galvanized, they’re ideal for decks, fencing, repair work, and wood-to-metal assemblies exposed to outdoor conditions.

Full-Length Thread for Strong, Versatile Fastening

With coarse threads running the entire shank, these bolts provide maximum holding power across materials of varying thickness. Meeting ASTM A307 Grade A specifications, they’re a go-to for contractors, facilities teams, and industrial users who need reliable strength in harsh environments.

Key Features

  • Fully Threaded Shank: Offers consistent grip and clamping force along the entire length.
  • Hot Dip Galvanized Finish: Provides enhanced corrosion resistance for outdoor and high-moisture environments.
  • ASTM A307 Grade A Compliant: Made from low carbon steel for general structural fastening.
  • Hex Head Design: Compatible with standard sockets and wrenches for quick installation.
  • Coarse Thread Profile: Delivers solid engagement in wood and mild steel substrates.
  • Versatile Applications: Ideal for decks, framing, fencing, and structural repair jobs.
  • Available in Multiple Sizes: Choose from a range of diameters and lengths to match your project 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

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!
