Rivet nut insert tool

Post by **Eck** » Wed Jan 03, 2018 6:11 pm

I have 2 7/16 rivet nuts that I need to install but having a hard time tracking down a tool that doesnΓÇÖt cost me an arm and a leg. Does anyone have a tool that will do that large of a rivet nut I could borrow for 5 minutes?

make one. A bolt and a nut. Drill the treads out of the nut. slide over the bolt. Screw the bolt into the nut cert. Turn the bolt while holding the nut with a wrench. I've done hundreds like this. No need for a fancy tool.

So you hold the nut down to keep the rivnut from coming up with the bolt?

Essentially yes, it is the ΓÇ£toolΓÇ¥ that keeps the rivnut flush against the panel as you tighten it & it expands. IΓÇÖd add a lock washer that looks like this between the drilled nut & rivnut so the rivnut doesnΓÇÖt spin as you tighten it.

I have a tool but not sure I have the die for that size. I think I have 3/8 is the biggest. I have also made a tool like above when the actual tool won't fit in tight spaces.

For sure use a grade 8 bolt and I find that a serated flange nut works great as the base of the tool. The rivnut must not spin as you tighten the bolt. Also put some oil on he bolt threads into the rivnut. I have had them gaul up before and destroyed the nut while trying to crush it.

Alot of companies just send a larger coupler nut (the 1" long nuts) with their products to use as a tool to install their products on jeeps.we get alot of that at the shop. The tool is just faster which is why I bought it.

I'll check when I get to the shop on what dies I have and can take a pic of how I do them with no tool if you want.

I may take you up on that, thank you. I just have two of them to put along my rear cab ledge that will be used to hold down my soft top bracket. Would be very easy to do in your parking lot in probably less than 20 minutes.
