Used these with my American Standard toilet after watching a couple of different YouTube videos about how to replace these tank bolts. Both videos suggested a similar bolt set up so I purchased these and they worked flawlessly. Installation was super easy and I really appreciated the wing nuts since my giant sized hands had trouble maneuvering enough to get the old hex nuts out.

The old tank screws were starting to leak in my master bath. They were roughly 15 years old.These are slight overkill on the amount of gaskets, but honestly I prefer it. Easy to install and no leaks at all. I’ll probably get a couple more sets in the future

This attchment set replaced a plastic connector which was the original equipment which broke. I highly rfecommwnd this metal; stainless for its durability and eaase of installation.

This is a well designed set for its intended use but the use of wing nuts instead of hex nuts for securing the tank to the toilet is an engineering mistake. It is impossible to get the wing nuts tight enough to prevent leaks at the main gasket with only fingers to tighten the nuts. Hex nuts would have been much better as any adjustable wrench could have been used to secure the right tightness. Unfortunately the bolts are Metric so the correctly threaded hex nuts may not be available in all locations such as where I live.

I didn't even remove the water tank to install this. I only need to change one and I wasn't sure this will actually hold. But I got enough room to fit the washer in the bottom. It's been 2 months and no leaks.

Leaks and does not seal, junk quality that doesn't work. I wouldn't recommend this at all.

The tank still leaked. Bought the actual American standard brand and that worked. For any other toilet this would be a very good product.
