Review on 100Pcs M6 Metric Rivet Nuts, Aluminum Flat Head Threaded Insert Nutserts for Automotive, Furniture, and Decoration - Keadic Product by Carta Gutierrez

Good nuts, cheap for 100. Well, there were 99 in the pack, but who's counting. Still great value for money. Good customer service too. I marked a spot 6.5" above the slide for the bottom hole, put painter's tape on the aluminum frame, started with a very small drill bit, a 3mm or similar bit and finally a 19/36" bit. This hair is larger than Rivnuta. I drilled a hole, removed the paper and inserted a rivet nut. Used 2.5 inch #5 thick nut bolt is larger than 5mm bolt. Hold the nut with a wrench, tool or pliers and tighten the 5mm bolt until it pulls the nut out of the frame wall. Make sure you use a nut with a grip on the front so the rivnut doesn't turn. Tighten the bolt until the Riving Nut is secured to the bike. Do this twice for the two holes holding the bottle cage. You can damage the first rinut, but the second will be tightened perfectly. Learned from cyclist RJ on YouTube. Much luck.
