If you have been doing some sort of manual labor at home that consists of DIY projects then chances are you have encountered rivets during your projects at some point. Rivets are the most underrated tools that we have when it comes to hardware tools. As we were trying to find more and more about rivets we came to a conclusion that there is not enough information regarding rivets. So here we are writing a publication that will hopefully consist of the information that not many rivet users will have known before. If that is not the case then we will hopefully cater to the beginner user of the rivets. Hopefully this useful information will help someone out of our readers. So let’s get into the details.
A little heads up for our readers.
In this publication we will be discussing:
- Tools for Rivet
- Rivet Strength
- Rivet Joint Material
- Rivet Measurements
Tools for Rivet
A rivet is usually placed on any object either via a hammer or a specially designed rivet gun. Now when you choose the rivet gun for placing rivets you have to consider few things to make sure that you choose the right rivet gun for the job. The basic things you have to consider are the power and air pressure rating along with nosepiece type. These things can be consulted with the manufacturer’s support team or you can finalize on the decision regarding these points by knowing the requirement of your task.
After these points are cleared off the next thing that you have to consider is the clearance. This factor is probably the most important of all. The clearance space of the rivet gun is determined in close space by measuring the space between the wall and the spot where rivet has to be placed. If the head of the rivet gun doesn’t fit between the space easily then you will probably have to go for a smaller rivet gun to get the job done.
You can however, in some cases solve the issue of clearance by using a nosepiece extension. The nosepiece extension can add up to an inch of extended reach on the nosepiece of the rivet gun. It is recommended that you place the rivet into the material from an unobstructed side it will be easier to do so from that side.
Now about the rivet strength, rivet strength is the most important thing you have to keep in mind if your placed rivet doesn’t hold up the joint together you probably have not placed it perfectly or you have the wrong rivet for the job. Manufacturers recommend specific hole sizes that are suitable for the rivet they produce. The smart thing to do here is that you should consult the parameters set by the manufacturers and follow those parameters to select the perfect rivet for the job.
There can be an issue regarding the alignment of the holes that need joining. To address this issue you can use a slots in the joint material facing the setting tool with similar hole diameters to join the two metals together with full rivet strength.
The next thing to do when it comes to utilizing the full strength of the rivet is that you should properly join the two materials together perfectly. Let’s look at the example of a tube, if you are to join the tube with another piece it’s better to join the tube’s flat surface with the other piece. The reason behind it is that the flat surface provides the maximum rigidness and strength to hold the two metal pieces together. If you don’t flatten the tube surface and it remains as it is like in a cylindrical form, you can still make a joint by placing the rivet to do so but the strength of the rivet will not be as much compared to the flat surface joint. The thing you should absolutely never do is extending the rivet through both the walls of the cylindrical shaped tube as it will produce the weakest of the joints and will not long be strong enough to last as long as it will be intended to.
If there is a small minor gap between the two metals, as long as the rivet is supporting the both pieces from both sides, the gap is all okay. You can however, place rivets on both the sides of the pieces but that is a little extra and is not necessary.
Rivet Joint Material
When joining two pieces together with a rivet you have to take into consideration the materials of the pieces you are trying to join together. Usually rivets are used on stainless steel, copper and aluminium steel pieces. For maximum utilization of rivet strength and to avoid corrosion on the joints it’s best to use rivets that are manufactured using the same material as the pieces you are trying to join.
One thing to keep in mind regarding rivets and the materials is that the rivets don’t hold well on softer compressible materials. If you are trying to join two soft material pieces together then it is best to add support on the pieces so that rivets can grip well and provide a strong joint.
The rivet measurement and the material thickness is also an important factor to consider when creating a joint using rivets the rivet should always have the grip range equalling to the thickness of the two pieces joined together. The rivet grip should not be confused with rivet length as the rivet length will always be greater than the rivet grip. If the rivet grip is shorter than the thickness of the two pieces, the joint created by that rivet will be too weak to sustain pressure. If the rivet grip is bigger than the thickness of the two materials then it will interfere with the clearance of the rivet and the bigger rivet will also cost you more which is not necessary at all.
We have discussed earlier that the clearance is a very important thing to consider when it comes to selecting the right tool for placing rivet joints. If use rivet with bigger rivet grip than it is needed you will be creating an obstruction in the operation of your rivet gun and you will not be able to create a rivet joint as perfectly as you should. So take into consideration the rivet grip in respect to the piece thickness.
We hope you find this publication useful.
