Why Toilet Bolt Spins: 3 Main Reasons 

Toilet bolt spinning is one of the most common issues with older toilets. Among several reasons, a rusted bolt is one of the most common. 

Some of the most familiar reasons are-

Rusted Bolt

It is quite obvious for the bolts to get rusted as they are open to oxygen and water. And when the bolt becomes rusted it becomes decay-prone. And the decay leads to bolt spinning. 

It is difficult for the decayed bolt to hold the seat, hence it starts spinning. But it is quite difficult to keep the bolt moisture-free. In fact, tile problems can also cause trouble with rust.

Smaller Holes

Another common reason is that if the bolt is smaller than the required size, it might cause spinning. That means, smaller holes lead to the toilet bolt spinning. So it is really important to drill in the proper size of the hole for bolts. 

Perfect-sized holes help to keep the toilet seat placement proper and firm. 

Debris around holes

Exposure to moisture also causes debris. And the debris caused bold spinning. The fact is you cannot stop the moisture from getting in touch with bolts. If you have both shower and a toilet in the same bathroom, it is even more difficult.

And the worst part is, that the mixture of moisture and debris is dangerous for your toilet bolts. It plays the role of lubricant. And thus the bolts start spinning. 

But don’t stress too much about it. It’s a long process to occur.

The very first step for resolving the bolt spinning issue is to remove the old bolts. Toilets bolts are located on the ground to keep the toilet seat in its place. For removing bolts, you can use an adjustable wrench or plier as well.

One thing to keep in mind is if your bolts are still spinning, you cannot take them off. To stop them spinning, you have to narrow down the bolt hole. To do that you have to insert a screwdriver into the hole first. 

After that, hold the bolts with the adjustable wrench. And take it out of the hole. Don’t forget to take off the screwdriver along with the bolts.

If you find the hole is not as big for the bolt then you have to drill it bigger. So that it matches the bolt size. 

Step 3: Drill Holes Accordingly

After figuring out the bolt sizes and the hole sizes, you need to work on the holes. Make holes according to the bolt diameter. If the previous hole is small in size, just make it bigger by drilling.

If the hole is already bigger, try to shrink it. Maybe make new holes that match the size of the bolts.

What happens when you over-tighten toilet tank bolts?

If you over-tighten toilet tank bolts, it might crack the toilet tank. Or sometimes it can even break the bowl attached to it. Toilets are usually made of ceramic or porcelain. They are hard and prone to crack. Since the material is not flexible for blending or any kind of movement, it might crack due to over-tightening. 

Why does a new toilet move back and forth?

A loose flange bolt is a common reason for the toilet moving back and forth. Flange bolts are used for keeping the toilet attached to the ground. There might be some other reasons as well. For example, floor damage, sewage leakage, damaged flange, displacement in the flange, etc.

Why does the toilet keep spinning?

If the float of your toilet is set too low, it produces a weak flush. On the other hand, if it is set too high, it causes overflow, and a water spill occurs. The water level of the tank is basically controlled by an adjustable float. So it is very important to set the bolt properly to avoid spinning.
