Rivet Nut Tool Kit, 16-Inch Rivnut Tool with 15 Metric & SAE Mandrels and Rivet Nut Gun, 200pcs Rivnut Tool Kit Assortment, Nutsert Tool Kit with Carrying Case

First off, what is up with the weirdo name? That out of the way, overall, this kit is the most comprehensive nutsert kit that I've come across. It covers both standard and metric in all of the sizes most likely to be needed. I will say that even with the instructions, it was a bit of a challenge to figure out how to remove and replace mandrels. However, after a bit of playing around, I figured it out (the spring retracting sleeve is what I didn't catch). I tried it out on a few of the included nutserts and they crimped down nicely. The only thing that I don't much like about this kit is that you really have to spread the handles to crimp and space isn't always available.

If you work with metal, this rivnut tool kit is an essential tool to have in your arsenal. It's sturdy construction and the tool-free operation of mandrels make it perfect for metalworking tasks.

This is great for when you can't put a bolt & nut on, like bolting a tool box down, just drill a hole put a thread rivet in and bolt it down.

This rivet nut tool kit has been a solid addition to my garage. The tool itself feels sturdy and works smoothly. The long handles make it easier to install rivnuts without needing a ton of force, even on tougher materials.

It comes with a good variety of both metric and SAE mandrels, which has been really handy for different projects. Everything fits nicely in the included case, and swapping mandrels is simple enough once you get the hang of it.

I’ve used it mostly on aluminum and sheet metal so far, and it’s done the job well every time. Definitely a good value for the price—perfect for DIY and light professional use.

I have become such a Nut for Rivet-nuts. I wish I had started using these yrs ago
