Note that the rivnut is threaded all the way up until it contacts the body of the tool.

Frame three shows the actual installation process. Our tool requires an open-end wrench to hold the body of the tool while a hex key (Allen wrench) is used to turn the threaded portion. Turning the hex key will draw the rivnut up to its installed condition.

Frame four shows how a properly installed rivnut looks when compared to the one above it that has not yet been installed. Once the rivnut is installed you simply thread your fastener in, just like any other anchor nut.

In Frame five you see what’s happening when you install the rivnut. As the installation tool is turned, it draws the rivnut body toward the tool. The rivnut body starts to bulge, and then is pulled against the back side of the surface where it is being installed.

The result is a tightly installed rivnut that will not turn when the fastener is threaded in. When you need an anchor nut in a tight location, a rivnut is just the ticket.
