Originally, blind rivet nuts were developed by the BF Goodrich Company in the late 1930s to secure deicing boots to aircraft wings. They are now used to fasten a wide range of materials. These fasteners are often used in high production environments. They provide a strong and reliable bonding power. They can be used to fasten metals, composites, and fiberglass.
Using blind rivet nuts is very fast and simple. They can be installed within three seconds without the need for special tools. They are also highly durable and resistant to severe environmental conditions. They are also extremely economical. The unit price is much lower than other fasteners.
When installing blind rivet nuts, one must first find a suitable hole in the workpiece. This should be at least 0.1 mm larger in diameter than the blind rivet nut. The nut is then inserted into the hole. Once it has been positioned, the nut is screwed onto the mandrel of an installation tool. The setting tool then activates the nut and causes the bead to form.
There are two types of blind rivet nuts: knurled and continuous hexagonal shank. The knurled version has a round body and is often preferred over the smooth version. The round body provides additional safety against rotation and spin-out resistance.
If you wish to install a blind rivet nut, you should use a specially adapted installation tool. This can be a manual setter or a pneumatic tool. You can even use an automatic riveting gun.
