5/8" Hammered Square Head Bolt


Bolts are typically used for fastening items together. Used for both 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.

Exactly what I was looking for

The square plate washers and square head bolts were exactly what I was looking for and perfectly complement the hand hewn barn beam mantle that I installed in our new house. The packing for shipping was pretty abysmal though. Considering that I was very much paying for the 'look' of the product, it was pretty disappointing to find the bolts and washers just thrown in the bottom of a box where they could bang together during transport. There was more than enough paper in the box where the bolts and washers could have been better wrapped to provide at least some protection of the finish.

Authentic looking

We bought an old farm pump and one bolt was missing. We stumbled upon this site while looking for old bolts and nuts. We bought the "rusty" finish and it matches our old pump perfectly. We need 2 more so we will be ordering again. It took some time to receive order but that information was clearly stated on their webpage. Well worth the wait.

My husband built a new bed frame and we got a live edge maple slab as our head board. It is massive and beautiful. We wanted it to be secure but still just as beautiful. We searched for something everywhere. Then he came across your website! This was the absolute icing on the cake! They couldn’t have been more perfect or us more pleased with the bolts and washers. They are well worth the money if you are looking for that one of a kind piece for your home!

Real as real can be

These 5/16 inch bolts by 6 inches long are to go with the 1 1/2 square hammered black washers to secure a 24 inch by 6 inch thick log to a wall as a coat and gun holster rack. The realism is beyond today back to 1845 from the town Black Smith's shop. Can't get better than these. Thank you, Jerry
