United StatesIncredible Craftsmanship
I can't recommend Old West Iron enough. The attention to detail, functionality and beauty in the actual product and how it makes each project shine is just incredible. I will definitely be coming back to purchase their products for future projects with as many of my clients as possible, as well as adding some of their magic to my own home. Thanks Old West Iron!

United StatesBetter than the originals
I have built numerous historical (replicas) wood project for many years using traditional wood working tools and was always on the lookout for affordable square headed bolts and lags. Old West has them at affordable prices and almost limitless size selections. They are exactly the same as the originals manufactured up to WW ll. As an additional plus, staff was exceptionally helpful during my phone order and it was a pleasure to speak with a human who knew the product line. Many Thanks from a new lifetime customer.

United StatesAs Advertised - Great Products
Purchased some 5/8” square headed bolts. They took a long time to get to me, which leads me to believe they’re either making them to order, or purchasing from other. Regardless, the quality was good and I didn’t need them right away anyway. Would purchase again.

United StatesBest Architectural Hardware Site
First, this company was great to work with. They were responsive and my mistake in ordering confirmed they are extremely fair with their return policy. Second, it is worth noting this is one of only a very few companies that offer really nice architectural hardware with a customization approach. I searched the interweb a considerable amount of time. Be aware of the scheduling for customized items and make your plans early. They provide a flow sheet for timing from order to delivery so use it. Old West Iron will be my go to on my contacts list for any future custom hardware. I highly recommend you visit their website and click around on all they have to offer.

United States3" Outside Corner Angle Iron, Smooth with offset holes and hardware
From initial call to end product - team was fantastic. I called - not truly knowing what I wanted, and, they coached me through it on the phone. Offered ideas and alternatives. Worked to cut a custom size. Called back same day and next day just to ensure alignment. I am in Southeast PA, and we don't have groups near that have the authenticity of these products (at least that I was able to find). Highly recommended group to work with.

United StatesPerfect bolts for the brackets I installed.
My wife wanted no sag brackets for her book shelves. I found some heavy duty brackets and needed some bolts with the same look. Love how they look. It’s hard to find these bolts. Thanks for making them!

I spent a week searching the typical folks (e.g. McMaster, Grainger, etc.) for the "unusual." I can't remember how I found your site but it was like the clouds opened and sun came out! I really appreciate your effort to support the old traditions and the restorers.

Hello,
Yes, these lags are great for exterior use and our black finish is designed to protect the iron from the elements so long as any natural wear and tear is maintained properly.

Q:
Can order just one of a couple different colors? I will be ordering 600 total 3/8 x 3” but I can’t tell if ordering the unfinished and doing my Own wax treatment would be better than one of your colors. Pewter, aged pewter, gunmetal and rusty metal are the colors I would like to order a sample of and get coming right away

Q:
Sorry, novice here. Do you screw these in with a wrench and to keep from scratching the bolt, would you put a thin piece of cloth between the wrench head and the bolt to prevent scratching?

A:
Hello! So we usually recommend to predrill then screw them in by hand but if the socket is the exact size it can be done without scratching the head. Otherwise if you prefer using the drill with a larger socket and a piece of cloth between the two that would definitely help!
