If the specific size of rod coupling nut you need is not available in-store or online, please speak with an associate at the ProDesk at your local Home Depot and ask about them placing a special order for you.

Hello Alexandre, it looks like these coupling nuts are store exclusive items and only able to be bought in a Home Depot store. Unfortunately we do not sell it with online stock for purchase. If you are unable to see the store inventory or price it is most likely either not a stocked item in your area or no longer available for purchase from Homedepot.com. I would advise you visit or contact your local Home Depot store for pricing and availability. Please follow the steps below to localize your Homedepot.com: 1. Localize Homedepot.com using your zip code (My Store Location: Change) 2. Choose the store where you want to pick up the item (Make this my Store) We appreciate your business and look forward to serving you in the future. Thank you for shopping Home Depot!

The threads were smooth, and the zinc finish was of good quality. I was surprised that may order came in a pack of three. I bought the item, thinking I was paying for only one.

These are less than 7/8" long, meaning that IF you get two threaded rods perfectly centered you only have about 3/8" engagement on each rod. Add the fact that you lose the first 1-2 threads on a rod to tapering, and you end up with 4 threads or so of each rod to hold. I'm used to seeing coupling nuts closer to 1 3/4" providing much sturdier connections, and would only use these for the lightest duty project.
