RIVET Safety NUTS provide a clean and sturdy housing for bolts and screws to connect with when the mating material is too thin or weak to support the fastener on its own. These unique fasteners are also blind, which means they can be installed on one side of the mating material when the other side is not accessible. While their function is straightforward, they require specific tools for installation.

What is a RIVET Safety NUTS and How Do They Work?

To use these versatile Safety fasteners correctly, it is important to understand what a rivet nut is, how they work, and how they’re installed.

What is a Rivet Safety Nut?

A rivet Safety nut is a blind threaded insert that provides support in thin sheet materials when the clamping force of a bolt or screw would distort or break the mating material. The rivet Safety nut features a hollow threaded body to house the mating fastener so it does not make direct contact with the mating material, giving the Safety fastener a sturdy housing for the threads to grip.

The defining characteristic of a rivet Safety nut is its collapsible body, which is what secures it in place and gives it its “blind” nature. Instead of securing a rivet nut with a fastener on both ends, the flange (the head) keeps it in place on the accessible side of the application while a rivet nut tool secures the blind end.

Most rivet Safety nuts will bulge just under the mating surface on the blind side, clamping the surface between the flange and the bulge. Swaging rivet nuts have a smaller threaded end that protrudes from the larger top half of the body. The installation tool forces the small end up into the large end, which expands the larger section enough to firmly secure the rivet nut in place on the blind side.

How a Rivet Safety Nut Works
A typical rivet Safety nut application includes five main components: the rivet nut, a rivet nut tool, a mating material (the base material the rivet nut is installed in), an attaching component, and a bolt or screw. To install a rivet nut, drill a hole through the base material that is the same size as the rivet nut.

Next, attach the rivet nut to your rivet nut tool. You will need to thread the rivet nut onto the mandrel (a threaded protrusion uniquely sized for each type and size of rivet nut installation tool) on your installation tool and insert the rivet nut into the hole of the base material. The tool then pulls up on the rivet nut until it collapses. Each type of installation tool has a unique way of applying force to the rivet nut so it forms a bulge or swage on the blind side. Once this force is applied, remove the tool. The rivet nut is now ready to accept a bolt or screw and connect the attaching component.
