Another rivnut/ rivetnut post

Through my own trials of rebuilding, I've tried to find a reasonably priced tool to properly set the rivnuts that secure the steering column and heater box. I tried the bolt, nut, and washer approach, however I found it really difficult to keep everything straight. I really only succeeded in waisting a few rivnuts, and scratching up my freshly painted firewall. I'm sure it can be done that way, I just wasn't having much success.

Online, I found a couple cheap tools that imitated the nut and bolt method, but I knew I'd have the same problems. My search continued. Grainger and such wanted a lot, like $150 for the tool and 40 or so for the correct nosepiece and mandrel. 150-200 bucks seemed like too much for 4 rivnuts installed, even if I could be sure they were done correctly. I recently found a Northern Industrial tool (http://www.northerntool.com/shop/too...4105_200394105 ) for $69.99. After a discussion with them to make sure it could handle this, I bought it. All in all it was about $78 shipped, and though I haven't used it yet, it seems ruggedly built. I'll post again and give a review after using it. I just wanted to pass this info along, as I've seen several people ask about a cheap installation tool. Though this isn't cheap, it's cheaper, and has several mandrels and rivet pieces that come with it. If it works well, I'll be psyched to have it in my tool box.

It's funny these don't come installed on new firewalls, while smaller ones are installed for the door retaining hardware.

Pegsus Racing sells some keyed rivnuts and rivnut placement tools - very inexpensive.

So my buddy was fighting rivnuts on the Rovertym sliders for his DII. He in my opinion came up with an ingenius idea. He would drill the hole and then smear a tad of metal epoxy of sorts on there and let it sit for a bit before using the bolt and nut trick to compress and seat them. Worked like a charm. No spinning at all.

Just FYI

Just used it for the first time today. It was totally awesome. I can't believe I didn't buy this sooner. I totally feel the $70 +shipping is justified now, especially since it came with several different sized mandrels. They went in straight, first try (destroyed too many trying to cheap out before buying the tool)!

Now that I have this, I'm going to rivnut everything. Where have you guys been buying the rivnuts? I got them online from Fastenal, but they were almost a buck a pop. Is that pretty much the going price?

Ok so I'm a little slow. Did a quick search and still can't figure this tool out. Isn't this tool from Northern for a rivet? I can use this on a rivnut? Thanks

I had no idea what a rivnut or threadsert was until I finally needed one. W
hat they are is a round piece of metal with the inner part comprised of threads. You drill the recommended hole size in the sheet metal mostly where it is impossible to get a nut on bolt, you insert the rivnut, you then screw the mandrel into the rivnut and into what looks similar to a rivet gun and squeeze. (I am simplifying this a bit)
The process pulls the threaded insert portion of the rivnut through the center of the rivnut and pinches the sheet metal onto the exterior of the rivnut. Now you can fasten your botl to the sheet metal/rivnut hole. val-la

Thanks Clay,

I guess I should have been more clear. I know what a rivnut is, I am wondering if the northern tool rivet gun can be used to set a rivnut. Thanks

Anyone have a good source to buy just the rivnuts? I have owned a tool (similar to the one at Northern Tool) for several years but have run out of my supply of the useful sizes

harbor freight sells an assortment box. McMaster Carr is hard to beat.

The one from Harbor Freight ($12)works very well and includes an assortment of nuts. An extra assortment of nuts is about $10. For comparison, the Snap-on one is $100.

I'm getting a Troy Box for the back of my defender and I'm thinking it may be time to buy a rivnut tool for the install. Is there any reason why I should get a metric set versus a standard set? Not sure which one to get. Any recommendations? Not sure how much I will be using this type of tool, perhaps for a wing top install down the line so didn't want to go overboard on an expensive one, but don't want to cheap out either.

Thanks in advance!
