It won’t be arrogant of me to say that you won’t have any other way to embed a screw into sheet metal. Especially not if you’re intending to burden it some weight. The weight will crimp the rivet even more only to reinforce it.
Initially, the rivet nuts are far smaller in diameter, pushing the arms to widen it. And voila! you’ve got just the perfect hole with the perfect threading to slide in the screw. That’s the working principle. Yes, it’s a bit of a complex mechanism so pulling some DIY tricks won’t do anything of the sort.
Choosing the wrong one might cost a wider hole thus liquidating the purpose of riveting. So, let’s get the best rivnut tool out there.

Specifications to keep in Mind for Best Rivnut Tool
If you are looking for an indefectible tool, then you need to be familiar with the facets that make these tools perfect. So let’s get familiar with the strong attributes that you need to be targeting while searching for your ideal rivnut tool.
Construction Material
The most reliable material would have to be steel as it is not that heavy for users & there is no question about the toughness of the material. Carbon steel may be chosen for the body of the tool to deliver that durability.
Mandrels, as they come in contact with rivets every now and then, are mostly made of chrome-molybdenum steel. All iron bodies are also a good option and are slightly lighter. But such tools should come with a good coating.
The Mandrel and Sheet Thickness
Rivet sizes depend on the thickness of the sheet of metal you are going to work on. And as rivets are mounted on the mandrel or nosepieces, mandrels come in varying sizes. Rivnut tool manufacturers provide both metric and SAE size mandrels.
An M4 sized rivet nut would be good enough for about 2.5mm sheet, while an M4 one for 3mm and so on. So as an approximate rule, as the mandrel size increases a step in metric, the thickness levels up by 0.5mm.
Arm Length and Thickness
The handle length directly links to the amount of leverage it gives to your target. Usually, an arm that has a larger length has better leverage over the smaller length ones. To wrap up almost all tasks going for 11 inches to 16 inches would be a smart and versatile choice. Anything greater than 16 inches would add much weight to the tool since it’s a fight between reachability and bulkiness.
Something around 3mm is a near-perfect thickness for double metal arms. Ensure that the inside of the arms is hollow enough to balance cumbersome. Certainly, the arms should be well attached by a double compound hinge
Grip of Arms
Rubber grips have quite no alternative. Keep in mind that ergonomically designed handles will give you more comfort. For that, U bend handles are an excellent suggestion. Otherwise, go for ones that leave indents for fingers to maximize hand control.
Lever
The lever rod is usually set up between the two arms. It should come up with an adjustable screw having a decent diameter. Longer rods enable the user to access it frequently and is a better option for riveting multiple small nuts. Surely it adds weight to the tool as a cost of that.
Ease of Use
Most Rivnut tools have the feature of a quick change of mandrel so that you can easily change the mandrels of the tool by hand. This feature will save you a lot of time. Otherwise riveting for long projects would take forever.
Carrying Case
Having a rigid carrying case is not a luxury but a necessity for you. Carrying blow molded cases will give you a better option for organizing all your pieces together. Keep an eye on the handle of the case so that it doesn’t take up an extra bit of space. The molds are to be perfect enough to prevent movement and marring.
FAQ
Q: How is a Rivet size measured?
Ans: You will see that there are different sized rivets available for a Rivet nut tool. These sizes of the rivets are measured by the diameter of the hole that the rivet is being installed into. You need to ensure that you are inserting the right-size rivet into the right sized hole or else the rivet will go waste.
Q: How to remove a rivet that is inserted wrong?
Ans: There are a few ways that you can remove a rivet if it is inserted into the wrong size whole. Drill & grinder tools are ideal in this kind of scenario.
Firstly, you need to use the grinder to grind off the rivet as much as possible. Then you need to use the hammer to push the pin part of the rivet. Then you need to drill the existing part of the rivet out. But you need to make sure that the size of the drill is smaller than the size of the rivet & the drill goes directly into the center of the rivet.
Q: Can an installed Rivet be reused?
Ans: No, after rivet nut is installed to a material it cannot be reused. After you install a rivet you can remove it by drilling into the center of the rivet. After doing this operation the rivet nut will be unusable as its structure would be hampered.
Q: What kind of measures should I take while using a rivnut tool?
Ans; As the tool deals with metal parts, it is necessary to wear personal protective gear before working with it. To ensure the safety of yourself & others around you should always make sure you are not too close to the work material.
Always use gloves to ensure the safety of your hands. Using googles is essential as any flying parts or rubbishes can go into your eyes & damage them. Always concentrate on your workspace as danger can come from any angle.
Q: Why should I use rivets instead of screws?
Ans: Rivets are mainly used to hold the surface of two materials together quickly & efficiently. Usually thinner sheet type materials are assembled using these rivets, whereas screws are rather ineffective in this sort of situation.
