What happens here

The final method introduced is the use of rivnuts (also known as threaded inserts or blind rivet nuts). These fasteners provide reusable threads in thin materials where access to the backside is not possible. The video shows matching a rivnut to a bolt. First, a pilot hole of the correct size is drilled in the metal. The rivnut is inserted into the hole, and then a rivnut tool (a green-handled hand rivnut installer) is threaded onto the rivnut. The tool's handles are squeezed until the rivnut collapses and expands on the blind side, creating a secure, threaded anchor point. A bolt can then be easily threaded into and out of the rivnut.

Goal: Install reusable threads in metal without backside access using rivnuts.

Tools and materials

  • Bolts — Attaching to the installed rivnut
  • Cordless Drill Milwaukee FUEL — Drilling pilot holes for the rivnuts
  • Drill Bit — Creating pilot holes sized for the rivnuts
  • Rivnut Tool — Setting the rivnut by collapsing its body
  • Rivnuts — Creating reusable threaded inserts in materials with blind access
  • Sheet Metal — The material being fastened

What they say

Hide

And it's easily removable whenever you need to. But, what if you can't get to the backside? That's where rivnuts come in. They're reusable threads without needing access to the backside. Make sure that you match the thread to your bolt. Drill the correct size hole, insert your rivnut, thread on your rivnut tool, and squeeze the handle till it collapses. And now you got these threads that you can use over and over again. And there you have it. Four different ways to fasten metal, all with their own
