Installing plastic rivets can be done in a few different ways, depending on the tools available and the desired outcome. Plastic rivets, also known as pop rivets, are commonly used for a variety of applications, from automotive repairs to home improvement projects. Some methods for installing plastic rivets include using a specialised rivet tool, a pair of pliers, or even a small grinder or drill. When using a rivet tool, the rivet is placed into the tool, and pressure is applied to the mandrel, which is then inserted through the pre-drilled holes in the materials being joined. The mandrel is then pulled back, flattening the rivet, and the excess is broken off and ejected. For those without access to a specialised tool, a pair of pliers can be used to hold the rivet in place while the tab is pulled back, or a small grinder or drill can be used to remove the head of the rivet.

Using a rivet gun
While it is possible to install plastic rivets without a rivet gun, using one is still a good option. Rivet guns are inexpensive and can be purchased at hardware stores or online. They are also versatile tools that can be used for a variety of DIY and construction tasks, ranging from metalworking to leathercraft.
To use a rivet gun, first, make sure that you have the correct size of the rivet gun for your plastic rivets. The rivet gun should be able to fit the rivet size you are using. Place the rivet in the rivet gun, ensuring that the grooved shaft of the rivet is facing the correct direction. The rivet gun will grip onto the shaft of the rivet and put a push-pull force on it, pulling the pin while pushing down on the black mushroom-shaped crown. This force will pull the fat end of the pin into the base, forcing it to expand and sandwich the base material.
If you are using a manual rivet gun, you may need to hold the rivet gun in place with your fingers while pulling the metal shank with pliers. Vice grips may work better than slip-joint pliers for this task as they can provide more force without slipping.
For larger rivets, a pneumatic rivet gun may be required. However, do not use a pneumatic rivet gun when working with glass as it may break under too much pressure.
It is important to note that plastic rivets are not like conventional pop rivets. Instead of simply pushing the rivet through, you must push the metal shaft through the rivet, which will expand the back and secure the connection.

Drilling out rivets
First, decide on the appropriate method for your specific situation. For smaller rivets, use a drill bit to drive through the surface. If you are dealing with stubborn rivets that are difficult to drill through, you may need to employ an alternative method. One option is to use a grinder to remove the head of the rivet, and then bore through it. Another approach is to use a hammer and chisel to break off the head of the rivet before drilling.
Next, prepare your tools and the rivet for drilling. If using the drilling method, select a drill bit that is the same size as the rivet or slightly smaller. This ensures that the drill bit fits snugly into the divot. Before drilling, apply a few drops of cutting fluid or lubricant to the end of the drill bit to reduce friction and heat during the drilling process.
Now, you can begin the drilling process. Start by drilling into the centre of the rivet. Drill only about 60% of the way through, just past where the rivet meets the material. This leaves something to punch out at the backend. If you are using the hammer and chisel method, insert the chisel under the rivet's head and tap it with a hammer to cut off the head before drilling.
Finally, complete the removal process. After drilling through the rivet, use a punch or a chisel to push or shear it out. Alternatively, you can use an angle grinder to cut into the rivet, but this carries a higher risk of damaging the surrounding surface. Once the rivet is removed, you can replace it with a new one if needed.

Using pliers
It is important to note that standard pliers or a screwdriver should not be used to remove plastic rivets, as they can damage the rivets. Instead, a specialised tool with narrow hooked teeth designed to pull the heads of plastic rivets should be used.
When installing plastic rivets, it is important to exercise caution and ensure that the rivets are securely fastened to avoid any potential issues. It is also recommended to have a helper assist in the process, as it can be challenging to apply enough force with just one pair of hands.
While pliers can be used to install plastic rivets, some people may prefer to use a rivet gun or tool designed specifically for this purpose. These tools can provide more leverage and make the installation process easier, especially when dealing with larger rivets or tight spaces. Ultimately, the choice of tool depends on personal preference, the specific requirements of the project, and the tools available.

Using a wrench
While a rivet gun is the most effective tool for installing plastic rivets, it is possible to use a wrench as an alternative method. Here is a step-by-step guide on how to install plastic rivets using a wrench:
First, place the rivet in the hole and hold it steady. You can use a bench vise to keep the rivet in place. Ensure that you have a firm grip on the rivet to prevent it from becoming misaligned during installation.
Next, use the wrench to pull on the mandrel of the rivet. Apply even pressure when pulling the mandrel to ensure that the rivet is securely fastened. Continue pulling until the mandrel snaps off.
It is important to note that while a wrench can be used to install plastic rivets, it may require more force than other methods. For example, one person reported needing to use a lot of force when pushing down on the rivet with a box wrench while also pulling with pliers.
Additionally, when using a wrench, be sure to follow general safety precautions and wear appropriate protective gear, such as gloves and eye protection.
Although using a wrench is a viable option for installing plastic rivets, investing in a proper tool, such as a rivet gun, is recommended if you plan to install rivets frequently.

Using a grinder
While there are many ways to install plastic rivets, using a grinder is a good option if you don't have access to a drill or a rivet gun.
First, you will need to prepare the materials you want to connect with the rivets. Clean the surfaces of any rust, dirt, or debris with a cloth or sandpaper to prevent slippage. Then, use a leather punch, drill bit, or other tools to make holes in the materials at the point where you want to connect them. The holes should be as close in size to the rivets as possible.
Next, you can use a small grinder to grind off the head of the rivet. It is important to hold the grinding wheel parallel to the surface with the rivet. Approach the head of the rivet with the wheel of the grinder, and do not try to wedge the wheel beneath the head before starting the grinder, as this can break the wheel and send shards flying. Once the grinder is up to speed, slowly move it into position until you make contact with the head of the rivet. Hold the grinder in a steady and fixed position as it cuts through the rivet.
After removing the head, you can bore through the rivet or use a small punch and hammer to drive the pin partway through the hole to make a starter hole for the drill bit. Find a drill bit that is smaller than the pin and drill into the centre of it. Then, replace the drill bit with one that is the same size as the rivet and drill it out. Finally, you can replace the old rivet with a new one.
While using a grinder can be an effective way to install plastic rivets, it is important to prioritize your safety and use the appropriate personal protective equipment.

Frequently asked questions
You can use a rivet gun or a rivet tool. Some people have also used pliers, wire cutters, channel locks, vice grips, and a fork-shaped bar to install plastic rivets.
Place the rivet in the hole first, then push the tool on and squeeze.
The size of the plastic rivets you use depends on the thickness and weight of the materials you're joining, as well as whether the materials are likely to shift positions once the rivets are installed.
