Im looking for a well made hand operated rivnut tool. One that will do atleast 3/8".
Astro makes one. I've installed 50+ of the 1/2" size:

They have some other kit mixes for a few dollars less if you don't need the 1/2" mandrel.
Or just do it with nuts/bolts/washers...

I can't speak about the Astro one but I have the Marson 325-RN Heavy Duty Rivet Nut Setter and it is bad ***. I also have the smaller Marson one which is a nice unit for smaller threadserts/nutserts.....
I have the Marson 39315 that does up to 1/4" I think, though im not sure if there are mandrels for anything bigger that would still work with the tool. Works great, easy to use and utilizes steel ribbed rivnuts to give a little more bite to keep from spinning.
**** post of the week right there. Why even bother.
I'm nearly as fast setting rivnuts with a nut/bolt/washer as you can do with the tool...and it's way cheaper? And you can do literally any size this way? Why is that a **** post? Or are you just not aware of the alternative method?

I've got these 2. The Astro works well for the price & can pull the threads right out of smaller rivnuts if you apply too much force. But the thing is big & can't fit into tighter areas which is why I got the smaller one too. I choose this one cause the mandrels for the Astro fits my little one too & the little one came with smaller sizes that the Astro did not come with.

What is the model of the smaller tool?
Really like my hydraulic powered FSI D100 hand riveter. Plenty of power, small package.
Pricey, but very well built.

Been using that bolt and washer set up for over 20 years.. 6-32 to 3/8-16 with no issues
