I've used this tool to set about 50 RivNuts (1/4"-20 ) on two homemade motorcycle work benches; the RivNuts some 1/4" screws secure the plywood top to the frame. The tool is simple and easy to use, however it is the users responsibility to start the RivNut properly by maintaining good downward pressure until the nut begins to grip well, or in other words, it is not fool proof. As others have done, I did lube the friction surfaces with grease; the grease I used has moly in it so that it stays put. This RivNut tool has worked well for me.

Have not tried the product yet. Hoping the treads are strong enough to hold up on the pressure. Hopefully they are a grade 8 material. Easy to get parts at the local hardware. Had to check on that!

Weak threads. Can be much much better.

Simple, quick, effective. I use it to put inserts where door closer arms pull out of the door frames at the Academy. Dont need a tool often enough to warrant the typical expensive rivet type tool. This one works great.

The pic is a tad bit deceiving in it's actual size. It's small! Probably better for aluminum or brass rivnuts but my needwas for steel. I have used it twice without fail and need it to work for two more installations. If I was installing steel riv's all the time I would either get a larger version of this or an actual rivnut tool kit. The main concern with the steel is that the 1/4" tightening bolt to collapse the rivnut may eventually snap and leave a partial install. But so far so good!!

Works good. Not fast but I’m not doing high volume so it’s not a concern. So far I used it to mount a fire extinguisher in the truck bed and re-attached the garage opener to the door when sheet metal screws ripped themselves out.

Serves its purpose for those occasions where an actual rivet tool will not fit in the space. - A drop of oil on the tightening screw helps a lot. This is not meant to replace an actual rivet nut tool. An actual rivet nut tool pulls straight vs this small screw that has to turn, sliding the threads against each other to pulling at the rivet. Siding threads = more friction and also wear. A person cannot expect it to do the same job as a professional rivet tool but Whenever I have needed this, it has worked well.
