Well built tool but the mandrels seems to be not tempered properly. I ordered the rivnut tool for a small boat customization project. I broke the 1/4-20 mandrel after setting 5 rivnuts on the first use. Oops! I contacted Vevor about replacement parts and they sent me a new compete Rivnut tool kit. Well outstanding! I set about the last 18 or so 1/4-20 rivnuts making extra sure that everything lined up square as possible. That worked pretty darn good until the very last rivnut of the whole project. The location was in a bit of a awkward position and I could not completely square over the location, as soon as the rivnut started to seat, the 1/4-20 mandrel broke again. Once again I contacted Vevor and once again no parts. They offered me another complete tool set or a refund of $24.. I took the money mostly because I really don't need a 3rd set of rivnut tools with defective and non-placeable parts floating around. Really is too bad, their customer service is pretty good

It seems like ok quality but no good after doing 6 nutserts. Thread damaged. Disappointing!
