Nutsert for rear C-Pillar?

[Yellow Cake Kid]

Hi,
I am looking for a MOPAR part number for the recessed nutserts used in the C-Pillar to attach some factory tops or aftermarket cargo racks.

I had a nutsert break off and fall into the pillar.

I have several types of nutserts in my shop, but would prefer to replace the broken one in my Jeep with a factory-matched wide-flange style.

I am hoping someone can share a part number or a parts drawing description so I can source this part.

Thank you.

Here's a pic of the missing threads.

What am I looking at? Is half of the nut sert still stuck on the pillar? Is the round flat shape just the flange on a standard nut set that has been painted over? I think I may be overthinking this and just need to drill out the flange. Or maybe not?

Thank you.

It’s been a while since I installed my cargo rack is the hardware m8x 1.25 and is it a hex drive nut/rivnut?

The nut broke off the flange. Pop it out, pop the new one in and you’re back in business.

... is the hardware m8x 1.25....

Yes, the threads were m8 x 1.25tpi.

and is it a hex drive nut/rivnut?

I can't see the back of it, so that is why I am asking.

I'm hoping someone who has replaced one of these before can reassure me that the flat, round portion that appears to be the flange is, in fact, the flange from the original nutsert.

If it were gold tone, I'd know what it is. :-S

I'm just extra cautious about things I haven't experienced yet because I live far away from everything and would rather fix things right the first time.

Thank you!

Wild ass guess but I don’t have any first hand experience. Hopefully someone else knows

Thank you.

Most, if not all, of my experience with threaded inserts has been with various DIY custom fabrications.

I have never had to repair a factory install.

Same for me. If you didn’t already,, I would also ask Benny from @AllMoparParts.com here

never heard of one breaking off like that. what do you thing caused it? over-tightening perhaps?

When something breaks,, given enough time, I can always make it someone else’s fault.

I would say, yes, I certainly over-tightened it, but the insert actually broke while I was removing my cargo rack from the mounting.

That said, I carry a lot of weight on my cargo rack and use the Jeep almost exclusively off-road on the bumpy local trails.

I was removing my cargo rack because the steel L brackets that mount it to the Jeep were starting to tear in half. I pulled the rack apart to weld and fabricate a reinforced version of the L brackets.. I have gotten a good 5 years of service out of the rack, so nothing to second-guess there.

And, in truth, I would have tightened the mounting bolts even tighter if I had dared to.

Thank you.

you could hit it with an air chisel to knock it out and weld a reinforcement patch over it with an actual nut welded to the backside.

Hi,
Here is some follow-up information:

I used a 3lb mini sledge and an old, previously abused wood chisel to attempt to peel the flange away from the body. I was hitting it pretty hard, and nothing would budge.

I was reluctant to drill out the nutsert as I wanted to preserve the factory hole sizing so a replacement would fit nicely.

I used a metric step bit to drill the hole. I pressed the step bit in so that the transition between the 12mm and 13mm diameters was about level with the Jeep's body metal. In other words, I drilled a 13mm hole in the flange, while the hole in the sleeve was about 12mm.

At this point, the flange lifted easily when I hammered the chisel underneath it. I peeled the flange off and could see the sleeve's remains. The outer hexagonal shape was becoming evident.

I used a tiny punch to pop the sleeve off the frame, which revealed the cleanly shaped hexagon.

The factory hole is large enough to clear a 13mm (or 1/2") bit, so the next time I will not be bashful about drilling the hole out.

I could not find a matching nutsert locally, so I am placing an order and look forward to making an easy repair.

I hope this helps anyone else who wants to know what to expect in a similar circumstance.

Thank you.

Thanks for the follow up. Are you thinking it’s the Mopar part? I’m good breaking things so I love to see the fixes.

 

[Yellow Cake Kid]

I am going to try the generic options that appear to be the same form factor.

Once I learned that the hex-shaped versions existed, it was easy to find them listed at parts sites.

Thank you.
