There are a few reasons why toilet bolts may rust out.


The majority of toilet bolts are made from some type of chromium alloy and will rust in water. Or, the bolts are not made of rust-resistant metal. – this one is the most common cause of rust bolts.


It is also possible that the bolts were not tightened down enough, allowing water to get in and cause rusting.

Sometimes, when the bolts are tightened down, the bolt can twist slightly. This is called a Helicoil – and if it’s not done correctly, the head of the bolt can be compromised.

If this happens, then the bolt has to be replaced.


The wrong installation sometimes ends up with a different issue like rust and leakage.

Another probability is that the bolts were not installed properly and are not getting enough protection from the water and weather.

It is also possible that the bolts were not installed using stainless steel washers or locknuts, which can help to prevent corrosion.


This one is a rare case in that the bolts put off some gasses that may be rusting them.

In summary, there are many possible reasons for toilet tank bolts can rust, and more than likely, it’s a combination of the reasons listed above.

Remove stuck toilet tank bolts

To remove stuck toilet tank bolts, you will need a few tools.

You will need

  • · a wrench,
  • · a screwdriver, and
  • · a bucket.

Place the bucket under the bolt to be removed and loosen the bolt with the wrench. If the bolt is stuck, use the screwdriver to pry it loose. If it is very stuck, use a plumber’s snake.

If the bolts are stripped, you will need to replace them.

1. First, flush the toilet and remove all of the water from the tank by turning off the shutoff valve behind the toilet or using a bucket to bail out water.

2. Take off the lid on top of the tank and look inside for a small rod about the diameter of a pencil.

3. If it is present, there should be a circular metal ring around it with two nuts on either side of this rod holding it down to the part that actually flushes.

4. Remove these nuts using your wrench and pull off the bolt sticking out of the bottom where you bailed water out.

5. You can now remove the old toilet tank bolts. If there is no rod on the inside of your tank, look around for a small plastic piece sticking out of one corner of your tank — this will be where you place the new bolts.

Once you have placed new bolts, go ahead and put everything back together by reversing the steps you followed to remove the old bolts.

How to cut toilet tank bolts?

When any project or task that involves cutting through steel is necessary, you should use the right tools for the job.

However, there are multiple types of cutting tools available. Which ones to choose can be difficult to tell without first understanding your options.

Suppose you want to cut through stiff metal material correctly and with ease. In that case, there are seven different methods for doing so, such as using a hacksaw, Dremel tool, cutoff wheel, bolt cutter, chisel, hammer, grinder, or plasma cutter.

1. Use a hacksaw

One way to cut steel would be with a hacksaw. A hacksaw consists of a handle, blade, and frame.

The hacksaw blade is typically made of metal with teeth on one side that can be cut through steel.

To use the hacksaw method, you first need to secure the material that needs to be cut into place using clamps or other available methods.

Secondly, you would then take your hacksaw blade and fit it into the hacksaw frame. A screw on one end of the frame allows you to tighten the blade onto the frame so that it does not slip during operation.

You can then use your hands or a pair of vice grips to hold the handle while cutting through the material with your sawing motion.

2. Use a Dremel tool

A Dremel tool is similar to a power drill in appearance, except that it is designed for much finer applications than just drilling holes into material.

This tool can cut through metal, but it requires various types of attachments to do so.

With the proper attachment, a Dremel tool can be sanded, drilled, scraped, and sawed through metal.

The keys to using this tool are having the right type of shaft torque, being aware of heat buildup, and working with tiny bits that snap easily if they become dull.

3. Use a cutoff wheel

A cutoff wheel is another option for making exact cuts through metal.

A cutoff wheel consists of a round cutting bit covered in diamonds or other hard abrasives, which allows it to cut through metal.

A cutoff wheel can be used on a grinder, drill, or belt sander and does not require any additional devices for operation as long as the right amount of pressure is applied with each cut.

4. Use a bolt cutter

A bolt cutter consists of two jaws that are pivotally connected via a handle.

The end closest to your hand is shaped into a sharp point that allows you to puncture through the center of a bolt fully.

It is vital to use enormous pressure on each cut to get the most out of this tool, which can be difficult for some people.

The speed at which the wheel cuts will vary depending on whether or not you have properly aligned jaws with your material.

5. Use a chisel and hammer

A chisel and hammer is another option for cutting through steel. For this process, you would use a chisel to first score each line of the cut you wish to make, followed by striking it with a hammer every few inches along the area that has been scored.

The number of strikes needed can vary depending on how thick your material is; however, you typically recommend keeping the number of strikes between three and five.

This process is time-consuming, especially for larger cuts; however, it is effective.

6. Use a grinder

A grinder is another tool that allows you to make precise cuts through metal, although this one does not require as much manual input beyond turning it on or off.

There are two primary types of grinder: bench and angle Grinders.

A bench grinder is a larger tool with one wheel on the side and another directly below it.

An angle grinder is a smaller tool that consists of a cylindrical body with a small protrusion at the top where you place your material being cut and an angled wheel that spins just below this area.

These two wheels work via friction to help you make cuts through steel or other harder materials such as masonry or granite. The more abrasive the wheel on your grinder is, the faster it will be able to cut through steel.

7. Use a plasma cutter

Each method is helpful for different tasks and may provide better results when compared to the other options available.

This guide is about cutting off toilet tank bolts so they can’t be used again.

If your toilet tank has only one bolt holding it to the flange, then this method is not for you. In this case, you need to replace the entire flange if it has rusted out.
