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.

Looks great
Ordered bolts a bit too small but they look great and are exactly what i was needing
Old West Iron
It looks great, you've put them to good use!

Shipment never came.
I don’t know. I paid for it but it never arrived. I contacted the company and I was told that’s that.

Lots of finish choices.
Was able to consider multiple finish options before settling on black. Delivery was reasonable for a custom product. However, the shipment date and estimated delivery were not easy to come by.

First buy
First timer. I was pleased to see the service and speed I got from Old West Iron. And the Pyramid Square Head Bolts are great. I'm still working on the project they will be used in so no photos right now.

Here is our Textures and Finishes page https://www.oldwestiron.com/pages/textures-finishes
I think maybe what might working for you is our pewter or aged pewter. I would suggest our gunmetal which is a darker finish with blueish tones but it is an interior finish because it may rust quicker. Please email me if you have any other questions at office@oldwestiron.com Thank you!
