#Sheet metal rivet nuts quotes install#

I wasn't able to thread a bolt into that one because the misalignment causes it to bind, and I suspect this is probably the most common issue people have. I also tried 2 full squeezes, which actually deformed the alignment of the flange opening in relation to the threads that start deep within. That's when I starting looking deeper to figure out why it spun, and noticed how much burr was leftover from drilling the hole. 1.5 squeeze got it fully seated, but I was able to spin it using pliers when I applied the amount of force I expected to use with a socket wrench to tighten the last 1/4 turn of a bolt. I tested installation with a single squeeze and that was not enough to fully seat the plus nut in the leftover ceiling panel from my fan install. I was using the proper installation tool, the Astro 1450, which is made specifically for plus nuts. I’m beginning to rethink the use of plus nuts and may switch over to riv nuts for their ease of removal and lower price. The cross/plus part of the nut prevents pull out, but doesn’t do much (if anything) in regards to spinning. In the image, you can see that most of the holding power that prevents spinning comes from just the 2 ribs near the flange. If you don’t remove the burr, it will interfere with the installation of the plus nut/riv nut because they won’t be clamping down on a flat surface! They’ll clamp the burr on the backside, which is already weakened, and it easily allows the nut to spin with very little force when you later add your bolt.įor blind holes, you’ll need to use a round file or a pick-like tool to de-burr the hole. When you drill a hole in sheet metal, it will usually leave a burr.

I haven’t seen this mentioned online anywhere yet, so forgive me if it’s old news or common knowledge now in terms of installing plus nuts or riv nuts.

I was playing around with plus nuts and an Astro 1450 today to get an idea of how much force was needed to install them properly and came across something interesting that might help others.
