HOWDIA Coarse Thread 1.25mm Connectors for 1"/ 25.4mm Diameter wire shelving poles with 0.047"/ 1.2mm Thick, Pole Connector for 1″-OD tubing with a coarse 1.25 mm thread and hole ≈23 mm, 4 Pack

These worked perfectly to join together the Costco shelves we bought probably 15 years ago.

We bought these to put together to standard NSF shelves. This was the one part that for years was hard to find. Search over. The part works like the original: good fit, solid construction, with clean threads.

This product was not 1" and didn't fit my Home Depot HDX shelving-unit poles. They were too small and dropped right in rather than screw in.

Fit loosely, difficult to get threaded correctly. Hold good enough for a light to medium load, but wouldn’t try to load to the shelf max weight

Awesome. Speedy delivery and exactly what I needed. I had misplaced these 4 parts from my bakers rack a few weeks prior and needed to put it back together . Funny part is I found the the day after theres arrived. Haaa. So funny . Thanks Gizhome for selling this important part.

The picture shows a Seville Classics connector on the left and this connector on the right. Seville Classics uses a fine pitch thread, these connectors are not fine pitch.

I purchased my racks at Costco and took a flier that 1.2mm was the correct thickness. I was right. These are an exact fit and work great. Buy with confidence.

I lost one of these in a move and thought, "No worries, I'll just order another from the company that made it." They charge $5.00 or more for one. Nope! Fortunately I found these. They are strong, thread in easy, and now I have extras. I expect they will work with any brand of metal shelving that have 1" pipes.
