Nice product

Cool bolts. Only sort of issue I have is that the actual product color was a bit off compared to the picture when I selected the one I wanted. However, it's still works. David

Great finishing touch!

From the customer service, to delivery, to the actual product I am one satisfied customer. The product itself is very sturdy, beautifully made and gives the exact look I was wanting to add to my newly built kitchen table. Five stars all around!

Perfect lag screw for my project

I ordered 500 1/4" hex head lag screws and washers in oil-rubbed bronze for a stair and landing baluster restoration project. The previous owner spaced the balusters too far apart (a child could fit between them) so I needed to double them up. Also, the old screws were plain steel color, rather ugly. Rather than hide the fasteners, I decided to "own" them and use oil-rubbed bronze. The order arrived in about two weeks, nicely packaged. They look great, perform great, and the bronze finish does not rub off as long as you take care to use good tools and proper torque settings, etc. I'm very happy with these screws and washers. I searched the internet for quite a while for these, and Old West Iron had the best size/finish selection. I'll definitely order again for my next project requiring a lot of fasteners, and OMG I'm drooling over all the other stuff on their website! Cheers, Andrew

Rust head lag bolts

I've ordered a few times now from Old West Iron. Nice quality and quick service. I was looking for rust headed bolts to hang some old barn pieces. The bolts from Old West Iron dressed it up real well!
