Review on Speder 136pcs Rivet Nut Tool Kit - Rivnut Tool Set with Wrench, Threaded Insert, and Nutsert - M6/M3/M4/M5/M8 for Furniture, Decoration, Car, Trailer, Boat, and More by Dre Fowler

I used this to add M5 mounts for a bike water bottle holder. After measuring the bit for the correct size bit and drilling the hole, I proceeded to install the rivet nut. It took a while, even with instructions, to install the setter on the handle. The bit and holder are screwed in anti-clockwise, ie back from the normal state. It took me some time to realize that squeezing the handle helped and I know the tool roll back. Installing the bat was easy but impossible to know how tight to squeeze. Too hard and you will rip off the rivet. Too soft and the rivet spins in the hole when you try to screw the screw in. The rivet packs show the size but the individual nozzles do not. I found an M5 bit after testing it with an M5 rivet and marking the bit pocket with a marker. The tool is solid and seems to be holding up well. The set includes a wrench for tightening the bit, which doubles as a clamp for the tool handle. I would give it 5 stars but due to lack of labeling and barely adequate instructions. The plastic case is good, but too small for all the rivets and bits. I had to insert nuts and bits along with the handle. I would definitely recommend this tool to anyone looking for an inexpensive tool to add metric sockets.
