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.

Hammered square head bolt
Love everything we’ve gotten. These are the perfect accents for our custom furniture.
Old West Iron
That looks amazing! Glad to see your order has worked out so well for you!

Purchased a bolt four of them thought they were lags. They were not now being charged a lot of money to return for restocking. Not very happy about that.
I think it’s a really cool product when I purchased it. I thought I was purchasing a lag bolt it wasn’t a lag bolt and now I’m being charged a lot of money for restocking here not very happy about that.

Absolutely Love their Product
I have used their products for several projects now. I will continue to use their product because it gives a nice finished look to what we are building.
Old West Iron
Thank you very much.

Great look!
Love the bolts, but should have asked how high the threads went up the shaft for the 6inch size. Wish they would have been the full length, or atleast half-way up; my mistake for not clarifying. But overall, love them! Would definitely buy again
Old West Iron
We are so sorry, we will clarify more on our website thank you.

Love them
This was exactly what I needed to finish my barn door table!
Old West Iron
Perfect, thank you for the review.

Attractive, well made, authentic looking.
Old West Iron
Looks great! Thank you

Rustic fasteners were perfect and staff is great to work with
I ordered hammered square head bolts and cap nuts for a project, then needed some rustic washers to make up for my having misunderstood the measurements. The Old West Iron staff were super helpful and arranged for the washers to get to me in time for the installation.
Old West Iron
Thank you, we're glad to be of service to you and look forward to helping you more.

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.
Old West Iron
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.
Old West Iron
Thank you and we're happy to hear this!

Perfect Finish Detail
Square hammered washers and 1/4" Square bolts, the perfect finish detail to our walnut and cherry mantle.
Old West Iron
Thank you for this positive feedback! looking forward to having you again!

Very pleased
Square head hammered bolts were the perfect detail for my fireplace trim project.
Old West Iron
I'm sure they pair just perfectly together! Thank you for sharing!

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.
Old West Iron
We appreciate you and are so glad you found what you were looking for! Can't wait to work with you in the future!

Bolts
