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.

Conquest A307 Grade A Hex Bolts with Hot Dip Galvanized finish are engineered for strength, reliability, and corrosion resistance in tough construction environments. Designed for securing wood or metal components in structural and general-purpose projects, these hex bolts meet ASTM A307 Grade A standards — making them an ideal fastening choice for builders, contractors, and serious DIYers.

Each bolt features a durable 6" threaded section and coarse threading that provides excellent grip in a variety of substrates. The hot dip galvanized coating ensures long-lasting protection against rust and harsh outdoor elements — perfect for use in decks, post-frame buildings, infrastructure, and other exterior applications.

Whether you’re anchoring heavy timber or assembling structural steel components, these hex bolts deliver strength you can count on.

Features:

ASTM A307 Grade A Steel: Built from low carbon steel to meet standard structural requirements.
6" Thread Length: Offers deep, secure engagement in various materials.
Hot Dip Galvanized Coating: Provides superior corrosion resistance for exterior and high-moisture environments.

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!

Had just what I needed and quick ship!

Bolt

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