This is the first time I was using the Astro Pneumatic Tool ADN14 Rivet Nut Drill Adapter Kit to put in some Rivnuts. Once I figured it out, it went pretty well. The Rivnuts have a little superglue as well to try to give them more shear strength. It was all good until the clutch on the drill got changed and I pulled out threads on one of the rivnuts. I wasn't sure there was a problem, so I put a screw in and tried to use it to clear the threads. Then it got stuck. Then I tried to take out the screw and it broke off. Then I tried to drill out the rivnut with the screw in it, and then the real problem started. I've sent an e-mail with a picture to Sling for suggestions on how to repair the hole. I am guessing it will be a doubler, but we'll see.
