United StatesWell made and artistic too
These work great with the 3"x3" old fashioned washers also ordered and also finished the same way. Look fantastic and strong as the job needed. Will order more from here and already recommending to others.

Hello Jason, So very happy you liked the Natural Rust Patina! The process of natural rust is hard to keep from flaking metal as it is a natural rusting process. We do not clean off the threads as that would take off some of the rusting patina. Thank you so much

I am looking at using your 3/8 inch or 1/2 inch hammered hex lag bolt to mount a barn door ledger board for a large (200lb) barn door. I will be using 2 bolts on every stud over a 14 foot span. The width of the ledger board is 1 3/4" inch plus 7/8" drywall. Can you recommend if the 3/8" or 1/2" lag bolt is preferred and will a bolt in 3 1/2" or 4" be preferred. Lastly how many days would it take to receive these in Southern California. Thank you Robert

Hey there, I do not work for the Old West Company, I am just merely a customer so I am not sure how I came to receive your question. As a Professional Design Builder I’d say always go bigger when it comes to needing strength, the cost is not much more for piece of mind reassurance. I’d recommend using washers the bolt as well and yes the 3 1/2 should do the job for you :)

Hi Robert, For a lag, I would suggest the 1/2". If you want a bolt, I would suggest the 3/8". I just want to clarify since we get this mistake a lot - the Lags are screws (pointed tip), the bolts are threaded to receive a nut. The product page you asked this question on is a bolt. I want to make sure you order the correct product. As far as lead time, I would expect about 5-7 business days to receive depending on the size of the order.
