How to Install PlusNut With DIY Tool





Introduction: How to Install PlusNut With DIY Tool

About: Hello! We're Isabelle and Antoine, a couple dreaming of being on the move and ride more. We bought a Ford Transit van, converted it to a campervan and we are selling our house to make our dream a reality. We...

We don’t like drilling holes in our van! It could:

  • attract rust on bare edges
  • spread metal chips all over (almost impossible to remove and will attract rust)
  • interfere with the van electronics (!) (follow your manual’s no-drill zones, such as the Ford Transit BEMM)

There is a way to avoid drilling holes... PLUSNUT!

What is a Plusnut?
It is an insert that you install permanently in an existing hole. Once installed, a bolt can be fastened (and removed) into it. Voilà!


  1. will not create galvanic corrosion (if your van panels are also made of steel, most likely they are…)
  2. have impressive pullout strength: 1215lbs (for .030″ thick steel)
  3. covers a wide grip range (grip = van panel thickness) (for example, the 1/4-20 Plusnut grip range is .020″ to .280″)
  4. are quite easy to install with specific tool or DIY tools
  5. blind installation (no need to have access to both sides of the panel)
  6. can be installed in plastic or wood as well

Step 1: Tools Required

  • Carriage bolt (same type as your Plusnut. 1/4-20 Plusnut = 1/4-20 bolt.)
  • K-Nut (it’s a nut with an attached, free spinning washer. ). We found this type of nut will last MUCH longer than a regular nut (a regular nut will last for 1-2 uses only as opposed to 10-15 uses for the K-Nut)
  • Box Wrench (or any drilled plate would do. This is just to prevent the Plusnut from rotating when upsetting)
  • Vise Grip
  • Wrench (for turning the K-Nut)

Step 3: Insert the Plusnut in the Hole

Step 4: Insert the Box Wrench, K-nut, Carriage Bolt and Secure the Vise-grip to the Carriage Bolt.

Step 5: Upset!

Step 6: Remove the Box Wrench, K-nut and Carriage Bolt. That’s It!

    Nop. We have no product to sell, so
    no business, so no advertising.

    Our Story:

    We’ve been
    converting a cargo van to a campervan during the last year, from scratch, with
    basic tools and basic knowledge. We’re now selling our house to travel for a
    year in the van across America. We detailed
    everything from our experience in our “Build Journal”, so others can benefit
    from our learnings and, maybe, be inspired for their own conversion. We
    honestly believe the Build Journal is valuable information.

    So here’s the deal:

    you are building your own van and you lurk onto our website to get some
    information, then you might end up buying a product by using any of the link on
    our site. In that case, Amazon will give us a small commission. You pay the
    same price as if you buy it directly from Amazon. That being said, I don’t feel
    like I’m cheating or doing something wrong. In fact, Instructables is OK with
    this practice (please read the rules).


    Plusnut are more tolerant to oversize or damaged holes, easier to install with DIY tools, greater pull-out strength & wider thickness range.

    Rivnut holds by expanding around the edge of the hole, while the Plusnut holds with the "petals" behind the hole (see pictures in this instructable).

    That's it! Hope that helps!
