With your DIY tool assembled in the order described above, thread it into the insert until it bottoms out. Put a wrench on the oversized nut to prevent it from spinning and a socket on the bolt head. Now, while holding the box wrench, start tightening the bolt. This will collapse the rivet nut on the back side and lock it into the hole. Now you can just back the bolt out of the insert. Install the rivet nut Increase the size of the drill bit to widen the hole until the rivet nut fits.
Swap out the drill bit for one with a larger diameter and place the end of it into the hole you made with the smaller bit. Bring the drill up to speed slowly and apply pressure to it. Drive the drill bit through the hole to create a wider opening. Try sliding the rivet nut into the hole whenever you change bits to see if it fits.
Whenever it slides into place, stop increasing the size of the hole. Part 2. Connect a mandrel and nosepiece that fits your rivet nut to the tool. Slide it into the tool and screw on the nosepiece that secures it and allows you to thread your rivet nut onto the tool. Open the handle of the rivet nut tool. The handle of the tool needs to be loaded up so you can drive the rivet nut into the hole and install it.
Screw the rivet nut onto the nosepiece of the mandrel. At the end of the mandrel is a threaded nosepiece. Pull the end of the mandrel back and wind the adjuster. With the rivet nut flush against the end of the tool, pull on the back end of the mandrel. It will slide back a little bit and allow you to turn the adjuster knob to tighten it.
Part 3. Insert the rivet nut into the hole. Hold the handles of the tool and slide the rivet nut into the hole. Squeeze the handles of the tool together. Use both of your hands to press the 2 handles of the rivet nut tool together. The tool will force the rivet nut to expand inside of the hole, which will connect it to the metal. Bring the handles together as far as you can.
Unscrew the mandrel to complete the installation. Unscrew the adjuster knob at the end of the tool and slide the tool off of the mandrel. Then, turn the mandrel to unscrew it from the rivet nut attached to the metal. You can now use the rivet nut to install screws to the metal.

Besides, other types of technologies such as weld-nuts and u-nuts require access to both sides of an application, which is not always possible.
In addition, rivet nuts allow applied forces in different directions and are hard to remove once installed. Torque-out is the force required to spin a fastener out of an application.
You can overcome this problem by using a rivet nut, which gives you the freedom to choose the ideal clamp load for one material and set a different torque for the joined assembly. Unlike bolts and screws, rivet nuts radially swell to the shape of the hole, hence preventing the application from weakening over time due to vibration. In addition, by maintaining the rigidity of the joined materials, the joint remains strong and reliable. Fortunately, rivet nuts can be designed to generate a slight bulge on the blind side of the bearing surface, hence increasing the pull-out.
When working with fasteners, it is ideal that you have a strong and durable rivet suitable for the job. Here are some features to put into consideration:. Consider this feature when you have a large load-bearing surface to strengthen the hole and prevent the rivet nut from falling through. Rivet nuts are available in round, smooth, hexagonal, splined, and square styles to prevent the fastener from moving at high torque levels. The closed-end rivet nut style prevents water and dust from entering the assembly, especially in the automobile assembly.
Some rivet nuts have wedge heads underneath the head to bite the mating material and hence prevent the fastener from freely spinning in the site. Put the rivet nut on the end of a soldering iron and let it rest for a minute or two. Then push it into place, and it will slide into the right hole. However, you still need certain tools, such as a bolt with a nut, a washer, and an internal star lock washer. You can use a flowdrill as a rivet nut alternative.
Besides, the flowdrill provides solutions to the problems encountered when using a rivet nut. Regardless of the type of rivet nut you have, they are all blind fasteners, hence robust, reliable, and vibration-resistance. A rivet nut is an important tool for anyone working in the aerospace and automobile industry, where blind fasteners are crucial. With a rivet nut tool , you can form a lasting joint that cannot loosen even after being subjected to constant vibration.
