Bolts are typically used for fastening items together. Both used for structural and decorative applications. Our square bolts appeal more to a rustic design especially with our texture of hammered or pyramid. These square head bolts add just the flare you need for your project. When purchasing nuts and washers with this item you will want to select the same size as the diameter of the bolt.
We recommend using 3/8" diameter and above for structural applications.

Hammered square head bolts
The bolts are beautiful. We did need to leave them in the sun many days to off gas the paint. They did not fit into the 1/2” 8 point socket. Other than that we are very happy with them.

Thank you so much and we're happy to hear this!

Integrity
Nice to see a vendor who has integrity in what they say they do, when they can do it, and follow up on what the customer's thoughts on it were. All this on an order of, what, a hundred dollars or so. You'll see me again, and hopefully those that I shared my experience with.
