Toilet Tank To Bowl Connection Nut Type

[bottomsup]

I would like to know the type of nut and washers that I need to use to secure the tank bolt to the bowl. Since they go under the bowl and not exposed to water, can I use any type like zinc plated steel ones or do they have to be stainless steel or brass?

Usually the head of the bolts that hold the tank to the base part does go through the tank. https://terrylove.com/forums/index.php?threads/rustproof-toilet-tank-bolts.66630/

Use solid brass. Not that expensive.

If it's a Kohler Cimarron, then maybe plated. Most all others I see drop through the tank and then attach to the bowl. A rusting bolt streaks up the bowl pretty badly.

Not the bolts but the nut and the washer that go under the bowl. How about those?

Even though the newer, low-flow toilets use less water than the old ones, under some conditions, they can still get cold enough to sweat or, if in a shower room, the high humidity can get condensation...use brass or SS and you won't have an issue. Otherwise, you might.

I like a nice brass set with two nuts per bolt as well as two washers of each type per bolt, as well as a nice big brass bolt set. It's never gonna leak and never gonna rust. Something like this nice LASCO set, which is available in a lot of places: https://www.midlandhardware.com/659...ZM9sx8FYEdJA5B-stsrOoSn7RPzksyTBoCyQgQAvD_BwE

I also found and used a nice Toto set at one time.
