    Default Rivnut/Zebranut setting tool

    How many of you use rivnuts or zebra nuts? I have made a tool to set these very convenient pieces of hardware as I do not see my way clear to spend R800 on a tool that I wont be using all that often. I used it today to set a few rivnuts on my car which I am busy working on. What do you think? Anyone got another idea?

    I normally just use a pice of 3mm steel, a bolt and a nut.

    The rivnuts I have put in (two in existing holes in the truck's chassis and 4 others for feet in a lathe table I made) are just a little larger and will not be set with an allen key though. That was a 17mm socket and a power bar.

    That tool looks the business though

    Before I knew how these things work I bought a Fascor set from Makro.

    The first rivnut that I set was a 12mm and I also just used a couple of washers and some flat bar and two 19mm spanners to set it and it worked quite well. It was only a once-off on my car to mount the bumper. The bolt had seized in the captive nut inside the front frame and in trying to break it loose the captive nut was torn loose.

    I just don't put in rivnuts too often to worry making one. I think I've put in 6 rivnuts in as many years. But well done - the tool you have made looks excellent.

    I previously also did it using nuts and a self built device. Then I saw my mate set one in a few seconds and bought a rivnut setter. R800 bucks. I have gotten more than that back in beers from mates who borrow it. We do share the beers though.

    Make sure that the bolt and nut are high tensile steel, 8.8 or even 12.9 will do the job.

    Nice job. I take it the nut against the cylinder is what you use to turn so as to compress the rivnut. What is the second nut for. Just a hint, if the nut against the cylinder is used to turn, add a sacrifice washer between nut and cylinder, then you won't end up wearing out surfaces.

    This, seriously unless it a one off use just buy the tool.

    I'm not disparaging those making their own tools, its always great to see ingenuity. But for the majority of us its cheaper in the long run (time = money) to buy a proper tool

    Pricey but its a really well made tool

    I have built an interior for a campervan and used this method to set probably 20-40 riv-nuts without too much hassle.
    Just use a ring spanner and socket and ratchet or even a battery powered drill.
    For me, I would have to do this on a daily basis to justify buying the tool, but for a once-off job, this method definitely works 100%

    I have exactly the same set up. Question, how do you use a drill machine on this set up. I have to hold the bolt head and turn the long nut. With a drill machine how is this possible so that the rivnut and bolt don't spin in hole.

    Lastly, what size drills bit for M6 and M8 rivnuts.

    I hold the long nut and use a socket attachment on the drill to turn the bolt.
    Use a "grab" washer just after the rivnut. (between the rivnut and long nut)
    I'm at work at the moment otherwise I could have sent you a pic.
    Between the bolt and the long nut I use 2 flat washers lubricated with a bit of PTFE spray.

    The bolt must be able to spin in the long nut, not rotate on the thread.
    I measure the physical rivnut before I drill the hole. Because I scared that the rivnut might spin, I take a square or triangle file and rough up the drilled hole with a couple of grooves before installing the rivnut.

    Aah, so the bolt tightens up causing the rivnut to mushroom. Here I was holding the bolt still and tightening the long nut, no wonder it took ages.

    Yes, also make sure that the hole for the rivnut is not too big so that the rivnut has some resistance to stop it rotating in the hole.
