Rivnut Tool Needed (1 Viewer)

[Cruiserhead05]

I posted up in ChitChat but the way threads fly through that area, i doubt i'll get any responses.

Anyways, I need a rivnut installing tool to use three times and dont want to pay napa $130 for a tool i'll use for 15 min. and never touch again.


If anyone has one i can borrow that would be awesome.

This is for installing 3 10-32 sheet metal rivnuts.

Thanks
Brandon

Try this:

or you can make your own tool (steel strip)

RivetNut Installation

Start out with a strip of 12 gauge steel (~1/8") about 12" X 1". Near the end, drill a clearance hole of the appropriate size for a bolt that fits the nutsert.

Get a long class 10.9/Grade 8 bolt (same thread size as the nutsert), nut and flat washer.

Thread the nut onto the bolt until it's near the head of the bolt. Slide the flat washer onto the bolt. Now stick the end of the bolt through the hole in the steel strip.

Thread the nutsert onto the end of the bolt until the end of the bolt is flush with the bottom of the nutsert. Slide the steel strip and the flat washer up against the face of the nutsert.

Lubricate the bolt thread that's now exposed between the nut and the flat washer with a molybdenum lubricant (doing it at this point minimizes getting lubricant on the nutsert threads). Thread the nut down until it touches the flatwasher.

Push the nutsert into its hole.

Use two wrenches. One to hold the head of the bolt stationary. One to turn the nut. The steel strip should also be held stationary.

*** This is the key point *** By holding the steel strip and the bolt stationary, there will be no twisting force applied to the nutsert as it is tightened. As the nut is turned, the bolt will be pulled straight out, collapsing and seating the nutsert.

When the nutsert is very tightly seated, loosen the nut a little and then unthread the bolt from the nutsert.

Using this method with the steel strip, you should have no problem with RivetNuts being loose. I've installed many nutserts this way without any problem. Info from Brian Brown

Thanks,

I had never seen the cheap rivnut tool before.

Like i said, its only going to be used 3 times so perhaps it will do the trick.

thanks

The rivetnut tool can do 8M rivnuts, but it's kinda pushing it's limits. Just so you'll know. I've done a few with it, and you need to be careful with the installation. If I recall correctly, I had the manufacturer open up the slot to 8M in order to use the 8M hardware.

Good luck.
