### ⭐⭐⭐⭐⭐ Review
*by M***S on 25 January 2026*

I bought the NEXTACK Rivet Nut Tool Kit because I had a project in a tight space that required precision, patience, and probably a smaller human. Since I didn’t have one of those available, I grabbed this tool instead — and honestly, it might be the better option. First off, the 8-inch rivnut tool is basically the pocket-sized superhero of the fastener world. It slides into tight spaces like it’s been training for a Mission Impossible audition. I half expected it to hum its own theme music. The step drill bit? Beautiful. It chews through metal like it’s snacking. I’ve used drill bits that screamed in agony the moment they touched steel — this one just shrugged and said, “That all you got?” And the 80 nutserts… listen, I don’t know who decided to include that many, but thank you. I now have enough rivnuts to fasten every loose thing in my garage, my neighbor’s garage, and possibly a small aircraft. Using the tool is oddly satisfying. You squeeze the handles, the rivnut mushrooms perfectly, and suddenly you feel like a structural engineer with a PhD in “Making Things Stay Put.” My confidence is now wildly disproportionate to my actual skill level. Bottom line: If you’ve ever wanted to install threads where threads have no business existing — in tight spaces, awkward angles, or places your hands definitely don’t fit — this little kit is your new best friend. It works great, feels solid, and makes you look way more competent than you probably are. Would buy again. Might even name it.
