Rivnuts are freakin awesome. I've used them for alot of things from automotive to walk-in cooler panel repair. If installed properly , they last forever. I've installed as big as 1/2 inch rivnuts and they hold like no tomorrow ! They make a setting tool that looks like bolt cutters and they work great , the smaller hand squeeze setter works fine too. Little tip though , when you use them for the first time , practice on a piece of scrap so you get the feel of it. You can buy the rivnuts on Amazon in a multi-size kit for pretty cheap , I have'nt noticed any big difference in quality of the cheaper ones. After you see how easy and cool they are to use , you'll be looking for things to use them on, haha.
I agree with the above.
Practice first. It may seem like you’re wasting some of the rivnuts but seating them properly is key as well as finding or using the correct size for the hole. I would go mid range on price. High end not really worth it unless you are using the tool on a regular basis and low end…well let’s just say there’s a difference not only with the tool but the rivnuts themselves. There’s also size differences with the tool. Some are long and heavy duty and some are smaller for tight spaces.
There’s videos out there on using the tool and setting the rivnut. Depending on the application, some thread lock won’t hurt either but if set properly they can be torqued pretty good.
