United StatesOld looking is wonderful
The carriage headed bolts I purchased looked great in the bench I built. It was a remake of a 1780's South France bench ,turned out wonderful. The hand hammered bolts gave it the detail we needed. Tha nk you for making great products and fast service

United StatesPerfect items for my new desk
I recently purchased some 5/16" black carriage bolts, nuts, flat washers and lock washers from Old West Iron. These items were a perfect match for the butcher block top that I used for my new desk. I only wish I could attach a photo or two to this review so everyone could see who great these items worked on my project.

United StatesWorth the wait for our John Deere D
My son is restoring a 1931 John Deere D tractor. We LOOKED everywhere online trying to find replacement bolts and nuts. Come to find them at Old West Iron. Placed the order and anxiously awaited to see if they would work. The day they arrived he fitted them perfectly.
