Description

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.

The Conquest A307 Grade A Fully Threaded Hex Bolts are a top choice for general-purpose fastening where strength, full threading, and corrosion resistance matter. Designed to meet ASTM A307 Grade A specifications, these bolts are perfect for securing wood to wood, or wood to metal in non-critical structural applications — from construction sites to repair jobs and beyond.

Made from low carbon steel and finished with a hot dip galvanized coating, these bolts offer excellent durability in outdoor and corrosive environments. The fully threaded design allows for maximum grip across the bolt’s entire length, making them especially useful when clamping materials of varying thicknesses.

Whether you're a contractor building a deck or a facilities manager handling industrial repairs, these bolts deliver the performance you expect — every time.

Features:

  • A307 Grade A Rated: Manufactured to ASTM standards for reliable performance in non-critical applications.
  • Fully Threaded Shank: Offers strong holding power for versatile fastening across a wide range of material thicknesses.
  • Hot Dip Galvanized Finish: Provides enhanced corrosion resistance, making them ideal for outdoor or high-moisture environments.
  • Available Options: Choose from a variety of diameters and lengths to match your specific job requirements.
  • Hex Head Design: Compatible with standard tools for straightforward installation and removal.

Excellent service

I needed some long lag bolts for a tree fort. Fasteners Plus had the product and shipped quickly. Shipping was pricey, but the package was an unusual size and heavy. I could not find what I needed on Amazon. The one drawback was that I could not locate the appropriate nuts and washers on their website. I suppose I could have called. I would suggest to their web manager to link the appropriate washers and nuts when ordering bolts. I did find what I needed at our local Menards. Menards does not carry the desired bolts in the required length.

High quality - good service

I have always been impressed with the quality of the products. High grade steel for bolts, different grades of stainless steel, etc., all well documented and easy to understand for a home repair. This is a large geodesic dome with a huge deck on a hillside, so a LOT of challenges. And the one time I made a mistake on an order (earlier this year) a quick phone call got a very courteous response.

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!

Bolt

I bought 8” bolts to secure 2x10x20 boards for a pole barn. So far they are working perfectly.
