Review on 🛠️ CO-Z 380pcs Rivet Nut Kit: SAE + Metric Assortment for Versatile Applications - 14 Sizes from #6 to 1/2 inch and M3 to M12 mm by Brian Cox

Don't get me wrong they work as advertised but . : They have thinner walls than other manufacturers. In addition, the flange is smaller. I've used them and they work. Connect things to ensure power continuity. Drill a close tolerance hole so tight that you must use pressure (hammer) to force the insert into the hole. Then squeezing the riveting tool will hold the small side slots in place as you screw the bolt in. Also, using a bolt and at least two lubricated sliding washers, I applied a second torque and tightened prior to installing the hose bracket. So far the insoles are holding up well. If the insert is going to be used in a situation where the bolt will be removed and reinstalled regularly, I would buy heavier threaded rivets from a Tacoma bolt or similar. IMHO.
