Anyone used these or another type of fitting on LC radiators. This or another solution for fitting the plastic guard as it is a bit neat for getting a nut and washer in when fitted Cheers John

used them on things before, but not this problem. Alloy versions are much easier to compress than the steel ones, sounds obvious now ive told you but ive seen people struggle with stainless when alloy would do and be easier.

I've never had to use them but they do sound like they could be the answer to fix many things. Are you guys buying them singular or have you found a box/kit containing different sizes? Any links to suppliers of such kits?

I used M5 alloy rivnuts and I found there was a fine line between compressing the rivet and actually ripping the thread out of the rivnut, but I am crap LOL

Cheers guys
I have ordered some M5 ones from ebay and will have a go and see how they work out
I agree with jonw that it would be a bit tricky compressing steel fittings on those flimsy alloy tangs on the rad when alloy ones will suffice. After all they are only securing a plastic cover.
I have looked at various tools and I think I could make something up which will do the job but with a bit of care so I dont rip the thread out of the thing (cheers headcoats for the warning) when fitting. Will post some pics when they arrive and hopefully work

I use them all the time for various repairs/hybrid builds etc, you need to practice a little at first to find the correct setting for each size rivert nut and different material thicknesses, but once you have the settings, its a peice of wee wee after that, worth doing a few practices on scrap metal, saves stripping the threads as some do by being "over" enthusiastic lets say !

Haha good advice Dave I only need 4 for the rad grill but I have ordered 20 to experiment with as I expect a few errors to begin with. They were only a couple of pounds so cheap enough I am that "over enthusiastic" individual you have referred to John

This is a dilemma I'm having at the moment
On the TR frame I'll need some fixings for things like undertray, elec panel mounts Tec
Do I get brackets welded on as I build or use rivnuts 🤔
Oh the dilemmas

I would do a practice one using a torque wrench so you can find the safe amount of torque to use.

If you get a good set of Riv nut pliers, and read the instructions of how much to compress the riv nut, the pliers will have a scale on them that tells you how much you have compressed them, that way you don't rip the mandrel out of the nut
The rive nut just needs to grip the substrate and not spin
Use knurled ones they offer a better grip on the hole they go into

One was like a pop rivet gun and the other had a screw thread in the main body of the tool which was changeable depending what insert was being fitted and you had more control over the crush .

A set of rivnut pliers and a compliment of various sizes "nuts" are a must in any bike builders tool box. I use them personally on my builds and we use them in the garage all the time.

If anything its almost too hard to squeeze really, maybe i need to work out more lol

They make excellent replacements in a situation where you would normally use a nut and bolt through a metal collar . Simply push in a riv nut with collar at rear and just use a bolt . Sort of a semi captive nut.
