If you’ve been following along, you’ll know that I’ve been using Extruded Aluminum to frame my van conversion cabinets.

One of the things I love most about the Extruded Aluminum (8020) material is how strong it is. A huge factor to its strength is in the way that it’s fastened to the van.

How do I fasten 8020 cabinetry to the framing of my van?

When it comes to fastening 8020 Extruded Aluminum to the framing of your van, something you’re going to want to get very familiar with is Rivnuts. You’re going to be using a lot of them!

If you know how rivnuts work, then you know how to attach 8020 to your vehicle.

So, what are Rivnuts?

A rivnut (also known as a rivet nut) is a special type of nut that provides a threaded insert for bolts to be threaded into. It’s installed into a prepared hole in a piece of metal and secured prior to threading in the bolt.

A special installation tool is required to secure the nuts into the hole.

How to install rivnuts in your van

  1. Measure your rivnut then find a drill bit that matches the width. I use a caliper to measure the rivnut.
  2. Drill hole.
  3. Place the rivnut in your rivnut tool, placing it inside the hole, then squeeze the rivet gun. The tool uses compression to give a super tight fit into the framing of the van.

Now you have a nice threaded insert where you can thread machine screws or bolts directly into the frame of the vehicle.

Different Terms for Rivnuts

One tip, when using rivnuts, is that you’ll probably find different terms being used:

  • Rivnuts
  • Rivet Nut
  • Plus Nut

I found rivnut and rivet nuts to be the same thing. Plus Nuts, on the other hand, are a bit different. I’ve heard that plus nuts are actually a bit better but with the rivnut tool I purchased, it didn’t work very well as I wasn’t able to get the proper compression.

Rivnut Sizes

I’m doing a metric build. If you’re using wood, this doesn’t really mean anything. But when working with 8020 it does matter because I’m buying metric size extrusion profiles. I’m buying 30 mm and 40 mm. In the U.S. it would be one inch and an inch and a half. So I’m using the 30 series and 40 series, and my rivnuts match my bolts. My bolts are also standard or metric sizes.

I’m using:

  • M5
  • M6
  • M8
  • M10 (although if I did it all over again, I probably wouldn’t bother using this again as it’s overkill)

The hardest part about using Rivnuts

So now that you know the answer to fastening 8020 to the vehicle is rivnuts, let’s talk about the hardest part of using them…

The hardest part about using rivnuts is the upfront planning that’s required.

When you use wood, you use wood strapping and you just know roughly where that strapping is. As long as you know where your strapping is, you can just fire in a screw there.

These rivnuts are precise threaded inserts into the vehicle so you have to know precisely where that threaded insert is so you can thread it through other materials, such as your ceiling panels.

I hope you’ve enjoyed learning how I use rivnuts to attached 8020 to the framing of the vehicle.
