Review on 🔧 HIFESON Hand Rivet Nut Tool: Manual Riveting for M5, M6, M8 Nuts (10-24, 1/4-20, 5/16-18 Sizes) by Hector Liamsi

Highly recommended. They have tiny needle bearings and run lightly, but require constant, even pressure with both hands. If I had to install 1,000 rivet nuts I might want to install a $500 air gun, but it works in tight spaces where a fancy gun would never fit. They come without instructions but are easy to use. In this set you need metric SAE and combination wrenches as well as Allen wrenches in different sizes. I suggest using ONLY hand tools. With a combination wrench and a hex wrench, you can easily tell by feel (the torque) when the rivet nut is fully seated and not being tightened. The impact tool can easily overstretch the tool and rivet nut and cause them to break.
