Description

3/8" x 1" 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 Hex Bolts in 3/8" diameter feature a fully threaded shank for maximum engagement across materials of varying thicknesses. Hot dip galvanized for superior corrosion resistance, these bolts are a go-to fastener for framing, decking, and general outdoor construction applications.

Versatile, Reliable Fastening for Wood and Steel Connections

Manufactured from low carbon steel and built to ASTM A307 Grade A standards, these bolts offer consistent tensile strength and durability in non-critical structural applications. The coarse thread profile ensures strong grip, while the hex head allows for quick installation with standard SAE tools.

Key Features

  • 3/8" Diameter Carbon Steel: Ideal for light to moderate fastening in construction and maintenance.
  • Fully Threaded Shank: Provides continuous engagement along the bolt length for secure clamping.
  • Hot Dip Galvanized Finish: Resists corrosion in outdoor and high-moisture environments.
  • ASTM A307 Grade A Compliant: Meets industry standards for general-purpose structural use.
  • Coarse Thread Profile: Ensures solid bite in wood and mild steel connections.
  • Standard SAE Measuring System: Compatible with U.S. construction tooling and sizing.
  • Hex Head Design: Installs easily with wrenches or sockets on any jobsite.

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!

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.
