Rivet Nut Tool buying guide

The rivet nut tool is behind the tough strength of riveted connections. If you fail to select a good rivet gun, it may jeopardize the basic structure of your workpiece. Here are some of the main concerns listed below that make high-quality rivet nut tools.

Types of Rivet Nut Tools

There are four types of rivet guns you need to know about for identifying which type you are purchasing.

Hand Rivet Gun

Hand powered POP rivet guns complete its tasks with a normal lever and squeeze facility. Hand-operated rivets are usually the cheapest, they offer a variety of rivets and generally made of steel with cushioned handles. It’s good for occasional use, but it is tiresome for long period riveting.

Heavy-Duty Lever Riveter

Heavy-duty rivets work with a wider range of rivet sizes. They are more heavy-duty, easy to use, reduce the energy required for work, and also come with a collection bottle to collect the mandrels after installation. It can be used in many job areas and installation is very simple. But the cost is slightly higher.

Air Rivet Gun

Air rivet gun or pneumatic riveters are a great choice unless cost is considered. Such rivet nut tools puff off the air under compression to drive the rivets out. You just need to put the rivet, get it into the prepared hole, and press the trigger. As the whole procedure takes place in the wink of an eye, they are best for a heavy load of tasks.

Cordless Battery Riveting Tool

Electric riveters are another solution other than pneumatic ones to reduce fatigue and cover a multitude of riveting at job sites. These rivet guns come with pre-installed batteries yet in a compact and lightweight form. Though recharging may drive a bit of annoyance, keeping an extra standby battery deals smooth.

Materials

Usually, the rivet guns are made of metals, but the type of metals varies. It’s basically three in number- aluminum, steel, and copper. Iron is also found to be used. Iron rivets are durable but heavier than steel. Rivet nuts are made of aluminum and steel.

Aluminum Rivets

Aluminum rivets are the lightest. In spite of their lightweight, they are very strong, durable, and capable of resisting natural corrosions. You will feel comfortable with this rivet in hand even working for long hours. They are ideal for permanent fastener applications.

Steel Rivets

Steel rivets are rugged, efficient, and an option for a wide range of permanent fastener applications. They are comparatively simple tools, composed of a shaft and with heads of different styles at one end.

Copper Rivets

Copper rivets are known as rustproof, sturdy rivets. They are capable of holding together many metals and permanent fastener applications. Such metal bodies include natural antimicrobial properties and excellent conductivity.

Size

Versatile rivet guns are compatible with almost all rivet sizes. For working in hard-to-reach places, size and strength both are needed to be considered equally. Professional-sized rivet guns are suitable for large projects. Rivet guns usually come in a wide range of sizes from 3/14’’ to 6/18’’.

Riveter size to metal thickness

The length of the rivet is needed to be as same as the thickness of both objects you are fastening. It should be 1.5 times the diameter of the rivet’s stem. For example, if you’re using a ½ inch diameter rivet to fasten two one-inch wide plates, the rivet has to be 2-3/4-inch long.

Handles

Handles of the rivet guns affect your comfort and adaptability. Ones that offer rubber or cushioned grip are considered as the most comfortable ones, especially for long period tasks. Steel handles are more durable but it’ll bother you in continuous hour work. Note that air rivet guns don’t need handles.

Compatibility

Rivets come in a broad range of sizes as mentioned and so it’s very important for the tool to be compatible. All rivet guns don’t support different sized rivets. Some guns may not provide nose pieces. The rivet guns that support most of the rivet sizes are more suitable for a large area of riveting opportunities.

Durability

Whether you’re an occasional user or an everyday worker, you have to check on the durability of the rivet guns. For small works, soft metal rivets will work well. But for large applications, rivets of aluminum, steel, or iron are best.

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.
