Why Do Toilet Bolt Caps Don’t Stay On?
It’s almost rare to see a toilet with its bolt cap in the right place. There could be quite a few reasons why it’s not staying in its place-

Rust is one of the main reasons for this problem. The metal parts can inhibit rust which makes it dysfunctional for the cap. Toilet bolts get rusted easily if left open as it stays close to moistures.
It can be medium to heavily rusted. To get rid of the rust you’re gonna need these components-
- White vinegar

Step-1: Collect The Bolts

Step-2: Make Rust Removing Solution
Pour ½ cup white vinegar into a bowl. Add 1tbsp citric acid and 1 tsp of baking soda in it. Mix all the ingredients well.
Put the metal bolts and nuts into the solution now. Once done, leave them for 30 minutes.
In this step, take an old toothbrush and add some toothpaste to it. Scrub it on the metal bolts afterward.
You’ll see all the rust leaving the metal. Repeat the process with all of the remaining bolts.
Step-4: Reinstalling The Screws
Once all the screws are rust-free, reinstall them in their position. Try putting the bolt cap on them. Hopefully, this time it’ll stay in its position.
Cause-2: The Bolt Is Bigger
Sometimes the provided metal bolts are bigger than they should be. In that case, you’ve to cut it short so the bolt cap stays on.
You’ll need a Dremel to cut the bolts. Use the same type of Dremel that cuts your ductwork.
Anyhow, here are the steps-
Step-1: Determine The Cutting Point
There’s no need to do any calculation for this process. Just leave a cm length above the nut of the bolt and cut it. Mark the point with a scratch.

The problem should be solved by now. But if it doesn’t, you’ll have to replace the bolt caps.
Cause-3: Faulty Bolt Caps
When your toilet flange is too high the bolt cap will keep popping out. In this case, you may need to change the flange. But if you don’t plan on changing the flange, replace the bolt caps.
The bolt cap comes with a washer. If you don’t have any particular product in mind, these are our suggestions-
Got your new bolt caps? Then let’s install them.
Step-1: Uninstall The Old Washer
Firstly, remove the old plastic bolt cap washer. It’s seated underneath the nut of the metal bolt.
You need to remove the nut with a wrench or plier. Once finished, replace the old plastic washer with the new one and reinstall the nut.
If the new cap is threaded, just remove the old washer. Insert the threaded type washer on the bolt. Rotate it clockwise and tighten it properly.
Step-2: Install New Cap
After installing the washer see if the bolt cap fits on the bolt. If it doesn’t then cut the bolt short with a jigsaw.
Use the same type of jigsaw that cuts ductwork. The cap should fit now. For threaded type caps just pop the cap over the washer and it’ll fit.
Hopefully, the cap stays in its place now.
