How a Tubular Rivet Works How a Tubular Rivet Works

In the world of fasteners a tubular rivet is a great way to fasten 2 different pieces together. Rivets are mostly used when you are working with aluminum, thin metal and even with plastics or leather. Rivets are made to mimic the look of smooth screws when they are set into the metal. However, unlike screws they are not easily taken out. You have to break off the rivets, or drill them out, in order to take the two pieces apart. 

Different Types of Rivets

There are 3 main types of rivets available to consumers today. They are normal, semi-tubular, and tubular rivets. They all have the same function, but have different levels of holding strength associated with them. 

How Regular Rivets Work

Rivets are like a staple for metal. The main function is to hold 2 pieces of metal together. This can be as a part of a frame, or a skin for a door or some other part. For normal rivets to work they must be placed inside a small pre-determined hole. This hole is the same diameter of the rivet body. Once the rive it placed through the hole there will be a certain amount sticking out the other side. This is then flattened against the metal side to form a secure fit. 

Strength Issues

One of the main problems with rivets is their size. If there is not enough on the other side of the metal then there is not going to be a lot of strength at the end point. The 2 pieces of metal will be able to easily be pulled apart. 

How Tubular Rivets Work

Tubular rivets give the look of a hollow tube that is inserted into the hole. The end piece, which is flattened out against the metal is hollow until it gets to the head of the rivet. The head of the rivet is where most of the strength lies in this type of rivet. This way there is not problem with how long the rivet is compared to the application it is being used on. 

Setting Tubular Rivet

Instead of place the tubular rivet into the hole as you would with a normal one, you use a rivet gun. This gun makes sure that you do not use too much force to fasten the rivet into place. When you use too much force you can compromise the metal sheet, or the integrity of the metal you are using. Set the rivet into the gun and line it up with the hole. As you press on the lever of the rivet gun is pushed the rivet through the hole and flattens out the end. 

Stronger and More Long Lasting

The tubular rivet gives the user a little more strength than the normal type of rivet. Once you bend the shaft to flatten it against the metal surface you have already caused some damage to the fastener. With a tubular rivet, this problem is not present because of the hollow tube. Because of this, the rivet side that is flattened can grip better, and the solid end provides the integral strength.
