any recommendation for good cheap nutsert rivet gun?
Never used one and see them on line so am assuming a normal rivet gun would not work for this, right? Took off a mirror on a Cougar and the inserts kind of just fell apart so to speak. Even though it's not my duty to go run out and get one of these tools it seems like a handy one that's worth having.

Any cheap $30 range ones would be nice. Suggestions?

When I was first learning about Rivnuts I went to HorrorFreight and bought one of thier kits that had Aluminum Rivnuts-it worked ok for light stuff, but then I decided that I wanted to put in Steel ones, so I bought them from McMaster Carr, and they offer a reasonably good Tool for putting them in-

I was making some support Rods with Rivnuts in them, and in a pinch I used the HorrorFreight Tool on a Steel insert-took a little more effort, but it installed them just fine-

I like the HorrorFreight style better (you can use one hand), but the McMaster Carr Tool is more robust-

Here's one from Hf:

Here's the ones I bought from McMaster Carr:

edit: dang it, I can't pull up the indiviual pages on the McMaster website, but they offer different ones-I wuould buy the HF style if I were going to do it again, although any of them work just fine-

You can do the aluminum ones without the tool. I tried the steel ones too but it was pretty tough. Just drill a hole the size of the bolt you'll be using into a piece of steel flat bar to use as a handle against the rivnut, and a nut on top of that to tighten down and expand the rivnut. The handle piece protects the rivnut surface and gives you a hard surface to turn the nut against.

You could probably do the steel ones with a longer handle piece and longer wrench. Use some lube under the nut.

That's good stuff Crownver, it's a little more refined than my way. :thumbup:

I have installed them for years without a tool. For a 1/4" Nutsert you get a 5/16" nut, put it in the vice and with a hack saw put some small cuts on the surface of the nut like cutting up a pizza. You then get a 1/4" bolt put it thru the nut with the cut marks on the bottom so they hit the top of the nutsert and tighten it with your hand tight. Put the nutsert in the hole then hold the nut with a wrench while you turn the bolt with a ratchet. And yes this was on aluminum ones.

Well I think that's a pretty good way too. The cuts in the nut are to grip the nutsert to keep it from turning, right? My way just relies on the friction of the nutsert in the hole, although once you have it started it's good. If the holes a bit big it might be a problem.

I have one of the Harbor Freight ones - works just fine for the aluminum nutserts. Last couple of times I went there, they didn't have more nutserts, only the whole kit.

I ended up building a hydraulic tool which works with the 1/4", 5/16", & 3/8" riv-nuts and clips into my HF "port-a-power" system. Those larger (steel) sizes are a britch even with a good hand tool.
